One service.
A connected approach.

Attract brings the visitor and Engage captures the enquiry. Nurture maintains its customer relationship management record, while Convert records the commercial outcome. This Scale service returns eligible outcomes to Google Ads and reports gaps in that connection. The next acquisition decision can then use evidence from sales, with a clear distinction between observed revenue and earlier qualification signals.

Is this your next step?

This service suits businesses whose sales happen after a conversation, assessment, proposal or other offline step.

Check the fit

Know what success means.

The first measure is whether the source process produces valid outcomes. We compare eligible CRM records with the events prepared and sent, then review acceptance and rejection information.

Explore the measures

Your questions, answered.

The practical details, when you need them.

Can we track offline sales without a Google click identifier?

Missing click identifiers can sometimes be addressed through enhanced conversions for leads, depending on your setup. Eligible first party customer details, such as an email address, can help connect an outcome with an advertising interaction. We assess the complete measurement setup before describing any gap as recoverable.

The review begins at the website. We establish which details were collected, whether the required tagging was present and whether the same customer information is available when the outcome occurs. A salesperson adding a different billing contact later can break that relationship. Available click identifiers remain useful and should be preserved through the enquiry journey rather than discarded because another matching method exists.

Older records require a separate assessment. Having an email address in a CRM does not mean every historic deal can be attributed. Import eligibility, event timing, data quality and permissions still apply. We describe any historical investigation as an assessment of available evidence. If matching cannot be supported, the record can remain part of your business reporting without being represented as an attributed Google Ads conversion.

Your handover explains the matching information used and the gaps that remain. Where prospective capture needs improving, we specify the required changes to forms or integrations. That gives you a practical route towards better coverage for future enquiries, while preserving an honest account of what the existing data can establish.

Should we send qualified leads, signed deals or payments to Google Ads?

Choose events that have a clear commercial meaning and can be recorded consistently. A qualified lead can be useful when sales take a long time, provided qualification means more than somebody opening an email or attending a meeting. A signed deal and a payment answer different questions. We define those outcomes with you and preserve the distinction in both the source data and the reporting.

Receiving an event and using it for bidding are separate decisions. We may recommend measuring several milestones while allowing a campaign to optimise towards an appropriate subset. Otherwise, a single customer progressing through several stages can create multiple rewards for the same underlying opportunity. That can confuse the interpretation of conversion totals and values, particularly when earlier estimated values sit beside actual sales.

The choice of bidding event depends on its reliability, frequency, reporting delay and relationship with eventual customers. A late payment signal might be commercially strong but too sparse or delayed for the intended campaign. An earlier accepted opportunity may offer a more usable starting point. We examine your actual sales process rather than applying a universal number of monthly leads or promising that deeper events always improve performance.

When the selected event changes, the measurement notes change with it. We retain the date of the transition and review comparable periods after allowing for your sales cycle. This prevents a change in what counts as a conversion from being presented as an improvement in customer acquisition.

How do you prevent duplicates when deals are edited or reopened?

We define the identity of an outcome using stable contact, opportunity and transaction references as appropriate. The specification establishes which record represents the imported event and when it first qualifies. Editing a phone number or sales note should not cause an existing outcome to become a new conversion.

The source process also needs rules for movement between stages. A deal marked won, reopened for an administrative correction and marked won again may represent one sale. A returning customer placing a genuinely separate order may represent another transaction. We discuss these cases with the team and test the selected behaviour, including the identifiers and duplicate controls supported by the import route.

Value corrections need deliberate handling. If an order is cancelled or its amount changes, the right response may involve an adjustment supported by the platform, a reporting correction or an exception requiring review. We establish the available options during implementation. We do not assume that resending a record with a changed amount will automatically replace an earlier conversion in exactly the intended way.

The handover includes examples of valid repeats and duplicates, plus instructions for dealing with exceptions. Monitoring compares the event log with source records so someone can explain why a transaction was transmitted, excluded or corrected. This makes the connection maintainable when your sales administrators or integration provider change.

What changes are needed for consent and customer data handling?

We review the data flow against your approved privacy approach and the relevant platform requirements. That means identifying the information collected at enquiry, what is later shared, the purpose of that sharing and the permissions recorded. Server delivery does not remove those responsibilities. Neither does hashing customer details make every possible use appropriate or turn the integration into an automatic compliance solution.

A practical specification sets out the fields permitted for transmission and the conditions under which a record must be excluded. It also identifies who maintains consent information when it changes. Website notices, consent controls and CRM properties need to describe and support the same process. If those decisions have not been made, we identify the questions for your responsible privacy owner before activating the relevant data flow.

Access deserves the same attention as the payload. Your advertising and customer accounts remain yours, and the implementation uses suitable permissions for the agreed work. We record who owns the integration and who can change its settings. Operational logs should support investigation without unnecessarily spreading customer details through shared documents, email notifications or unrestricted reporting views used by people who do not need them.

The service provides technical configuration and clear documentation of the agreed handling rules. It does not provide legal advice. Where your organisation needs a policy interpretation, your adviser supplies that decision and we implement against it, then check the actual behaviour with eligible and excluded test records.

How will we know the import works before changing campaign bidding?

We agree acceptance criteria before the connection goes live. These cover the meaning of the event, the expected source records, the value and date fields, and the treatment of duplicates or exclusions. A test should demonstrate the complete journey from the business action to the intended conversion action. A green status in an integration tool is useful evidence of connectivity, but it is only one part of that journey.

After controlled testing, we review eligible production records over a period that reflects the way your business operates. The reconciliation shows which records were sent, which encountered an error and which appear in the relevant platform reporting. Where counts differ, the notes distinguish timing or attribution limitations from implementation faults. That distinction is necessary before anyone interprets the numbers as evidence of campaign performance.

The campaign manager then assesses whether the event is suitable for the proposed optimisation strategy. We look for consistent definitions, timely delivery and a meaningful relationship with customer outcomes. Sparse sales or an unstable qualification process may justify keeping the event in reporting while further evidence accumulates. The recommendation includes the unresolved condition and the review that would allow the next step.

If a bidding change is appropriate, it should have a recorded baseline and an agreed evaluation period. Existing form conversion reporting can remain available for context. The implementation handover makes clear which events drive bidding and which provide supporting insight, so future account changes can be reviewed against the original intention.

What does Google offline conversions include?

Make the result of the enquiry visible

A submitted form tells you that somebody made contact. The useful commercial detail arrives later: whether the enquiry matched your service, whether a proposal was accepted, and whether a customer paid. If those changes remain inside a spreadsheet or customer relationship management system, usually called a CRM, campaign reporting has an incomplete view of the work your sales team is doing.

GRO connects a defined business event to a corresponding conversion action in Google Ads. The starting point might be a qualified enquiry with agreed acceptance criteria. It might be a completed sale with an amount and currency. We establish exactly what the event means before deciding how to transmit it, so the account receives a consistent signal when different people update customer records.

The connection provides evidence for campaign analysis and potential bidding inputs. Our scope covers the source record, import and diagnostic checks so your team can assess its reliability. Outcomes that cannot be matched stay visible, preventing gaps in measurement from disappearing when somebody decides where to invest next.

What the conversion connection includes

The implementation starts with an inventory of enquiry routes, conversion actions and customer data. We review website forms, relevant call journeys, redirects and the fields carried into your CRM. The agreed scope identifies which Google click identifiers and permitted customer details are available, how the outcome is timestamped, and which system owns the final value. Existing imports are included in the review to avoid parallel connections recording the same event.

We define the event mapping and implement an appropriate supported import route. Google now directs new offline conversion integrations towards its Data Manager infrastructure. Enhanced conversions for leads can use eligible first party customer details to support matching alongside available click identifiers. The route is selected after checking your account, data source and current requirements, rather than assuming an old integration guide still applies.

Handover includes field definitions, test evidence and operating instructions. We agree how cancelled orders, changed amounts and reopened deals should be handled, checking the selected route's correction capabilities. Any additional CRM restructuring, call tracking licences or ongoing monitoring are scoped explicitly. Your advertising account and source records remain yours.

How does Google offline conversions work in practice?

Trace one enquiry all the way through

We first follow representative records from arrival to outcome. This reveals practical breaks such as an embedded form dropping source information, a salesperson creating a second contact, or a payment being attached to the wrong deal. The evidence becomes a repair list with named owners. Connecting an unreliable status field would simply transmit the original problem more consistently.

Next, we agree the commercial event with the people who qualify or close enquiries. A quotation sent to an unsuitable prospect should not become a qualified opportunity solely because a document exists. Clear acceptance rules help sales staff make repeatable decisions. We also establish which event dates should be preserved when records are edited later and how repeat activity relates to the original acquisition.

We test controlled records, then reconcile eligible real outcomes. Rejections, timestamps, values and duplicate handling are checked before recommending a goal change. Reporting can begin while bidding readiness remains under review. The handover identifies who investigates failures and explains to the campaign manager exactly which signal is available.

Hypothetical example: enquiries for commercial installations

Imagine a commercial ventilation installer receiving enquiries for both planned installations and minor repairs. Its sales team records a site assessment only after confirming the building type, service area and likely project scope. This hypothetical business currently treats every contact form as equally useful, so the advertising account cannot distinguish installation opportunities from repair requests it is unable to serve.

The proposed connection records an accepted installation assessment as an early outcome and retains the eventual contract result separately. The CRM stores the original enquiry reference, qualification date and customer relationship. A signed contract has its own amount and date; a later receipt is treated according to the agreed payment definition. These records are not all added together and described as independent customer revenue.

An initial review might find that assessment records arrive consistently while completed sales take much longer. The practical decision could be to report both outcomes while using the earlier event for an eligible campaign goal. Subsequent reviews would examine whether those assessments reliably become customers. This is an illustrative design choice, not a result achieved for a GRO client or a prediction of advertising performance.

How do we decide whether Google offline conversions is right for us?

Check delivery, matching and commercial usefulness separately

The first measure is whether the source process produces valid outcomes. We compare eligible CRM records with the events prepared and sent, then review acceptance and rejection information. Missing identifiers, inconsistent currencies and dates recorded in the wrong time zone all need a named explanation. A successful connection status alone cannot show that the intended customer outcomes reached the correct conversion action.

The second measure concerns what Google Ads can attribute. Upload acceptance does not guarantee an event will appear as an attributed conversion. Matching eligibility, time windows, reporting dates and processing delays can all affect the comparison. We keep source totals and platform totals distinguishable, recording the reporting basis so a discrepancy can be investigated without quietly changing the definition of success.

Commercial evaluation examines qualified opportunity costs and their progression into customers using mature enquiry groups. Bidding requires dependable, timely data. We explain when the connection supports reporting but needs more evidence before controlling acquisition, and specify what would justify that step rather than treating launch as automatic readiness.

Start with the systems you already use

This service suits businesses whose sales happen after a conversation, assessment, proposal or other offline step. You can commission it as a starting point while retaining your existing advertising manager and website provider. We need access to the relevant conversion settings, source capture and outcome records, plus somebody who can confirm how the sales process works in practice.

A CRM is helpful, but the important requirement is a structured and maintained record of each eligible outcome. A controlled data source may be sufficient for a limited implementation. Complicated contact associations, several websites, multiple advertising accounts or payments held elsewhere add work because each relationship needs checking. We explain those dependencies in the proposal before choosing the integration route.

GRO connects technical delivery with the commercial meaning of each event, resolving ambiguous stages and giving campaign managers a usable handover. Responsibilities remain clear when suppliers share the work. Pricing follows the assessed scope, with connector charges and maintenance identified separately. Every pillar remains available as a starting point.
