# Sage Salesforce integration

*Sage → Salesforce*

**In short:** A Sage Salesforce integration keeps your finance system of record and your CRM in agreement: it pushes Salesforce accounts and closed-won orders into Sage as customers and sales orders or invoices, and pushes Sage invoices, payment status, outstanding balance, and credit-hold flags back onto the matching Salesforce account. Done properly it is not a nightly CSV drop - it is an idempotent, bidirectional pipeline keyed on a shared account reference, so sales sees real billing status and finance never re-keys a customer that already exists.

## What a Sage to Salesforce integration actually does

Salesforce is where the deal happens - the account, the opportunity, the order someone just closed. Sage is where the money is real - the customer master, the invoice, the payment, the credit limit, the balance the finance team actually reports on. When those two systems disagree, the cost is quiet but constant: sales promises a delivery to a customer who is on credit hold, finance re-keys a customer that already exists in the CRM, and nobody trusts either number at month-end.

A Sage to Salesforce integration removes the re-keying and the disagreement. It moves new customers and closed-won orders from Salesforce into Sage, and moves invoices, payment status, and credit standing from Sage back into Salesforce - each on its own trigger, each matched to the same customer, so both systems tell the same story without anyone copying figures between them.

## What data moves

| Object / event | Direction | Becomes | Notes |
| --- | --- | --- | --- |
| Account / Contact | Salesforce to Sage | Customer (Debitor) record | Created once, keyed on account reference written back to Salesforce |
| Closed-won Opportunity or Order | Salesforce to Sage | Sales order or sales invoice | Line items mapped to Sage products, nominal codes, and tax codes |
| Product2 / Pricebook | either direction | Sage stock item / price list | Agree a single master; usually Sage owns price, Salesforce mirrors it |
| Sales invoice | Sage to Salesforce | Invoice record on the account | Read-only in Salesforce so sales sees what was billed |
| Payment / allocation | Sage to Salesforce | Paid / outstanding status | Drives an at-a-glance payment state on the account |
| Outstanding balance & credit limit | Sage to Salesforce | Account fields | A rep sees credit standing before quoting or promising |
| Credit-hold / on-stop flag | Sage to Salesforce | Account flag | Blocks or warns on new orders for a stopped customer |
| Credit note / refund | Sage to Salesforce | Reversing entry on the invoice | Same customer and lines as the original, dated to the credit |

The exact field mappings, nominal codes, and tax codes are agreed once with your finance team and encoded in the pipeline. After that, nobody maps them again by hand.

## The details that break naive syncs

A one-off export or a generic connector app gets you 80% of the way and leaves the expensive 20% on your desk:

- **Account matching.** Salesforce identifies a customer by its 18-character record Id; Sage identifies the same customer by its account reference (the A/C ref, e.g. ABC001). Without a shared external-ID key, a sync matches on name, and "Muller GmbH" and "Müller GmbH" become two customers. The join must be an explicit reference, upserted, never a fuzzy name.
- **Create order, not before the customer.** Sage will reject a sales order that references a customer it does not have. The pipeline has to create or confirm the customer first, then post the order - an ordering dependency a flat export ignores until the import fails halfway through.
- **Tax and nominal codes.** Salesforce line items are free text and picklists; Sage demands a valid tax code and nominal code on every line. A product with no mapping cannot be guessed - it has to be held and flagged, not posted to a default account that quietly corrupts the ledger.
- **Which system owns which field.** Price, credit limit, and balance are owned by Sage; opportunity stage and contact details are owned by Salesforce. Sync a field in both directions without deciding an owner and the two systems fight, overwriting each other on every run.
- **API limits and delta sync.** Salesforce enforces a daily API call allowance per org, so a full re-sync of every account each run will exhaust it. The pipeline reads deltas by SystemModstamp on the Salesforce side and by modified timestamp on the Sage side, moving only what changed.
- **Idempotency.** Re-run a naive push and the same order posts to Sage twice. Every event carries a stable key, so a retry or a re-run never produces a duplicate invoice or a duplicate customer.

## How we build and run it

We treat this as a pipeline, not a scheduled export. Salesforce events (a new account, a closed-won order) are picked up by change event or on a schedule, validated, matched to the Sage customer by account reference, and posted as the right Sage document. Sage events (an invoice raised, a payment allocated, a customer put on stop) flow back and update the matching Salesforce account, read-only.

The pipeline is idempotent: every record carries a stable identifier and every write is an upsert on the shared reference, so a retry or a replay never creates a duplicate customer, order, or invoice. It runs on cloud-native, fully EU-hosted AWS infrastructure, so customer and financial data never leaves the EU - which keeps your DPA / AVV and your GDPR obligations clean.

And then we keep it running. Monitoring, alerting, incident response, and - critically - watching for Salesforce API-version retirements and Sage endpoint changes are our responsibility under contract. You get a named owner and an SLA. The flow of orders into finance and billing status back to sales stops depending on someone remembering to run a job.

## When this integration is worth building

If you close a handful of deals a month and finance can re-key them into Sage over a coffee, a manual process is genuinely fine and we will tell you so. The integration earns its place when order volume climbs, when sales keeps promising deliveries to customers who are on credit hold, when finance is maintaining the same customer twice, or when month-end reconciliation between the CRM and the ledger has become a recurring chore. At that point a managed pipeline is cheaper than the double-entry and the arguments over whose number is right.

## Frequently asked questions

### Which Sage product does this work with - Sage 50, Sage 200, or Sage Intacct?

All of them, but the pipeline is built for the specific one you run, because their APIs differ. Sage Intacct and Sage 200 expose proper web-service and cloud APIs; older Sage 50 installs often need the Sage Data Service or an on-premise bridge because there is no first-class cloud endpoint. We confirm your exact edition and version during scoping so the connection method is decided before we quote, not discovered afterward.

### How do you stop duplicate customers being created in Sage?

We match on a shared account reference rather than on name. A Salesforce account carries an external-ID field holding the Sage customer account reference (the A/C ref such as ABC001), and every write is an upsert against that key. If no reference exists yet, the pipeline creates the customer in Sage once, writes the new reference back to Salesforce, and every later sync joins cleanly. Fuzzy name matching is never the join key.

### Can sales see whether a customer has paid or is over their credit limit?

Yes - that is usually the highest-value direction. We push Sage invoice status, outstanding balance, and credit-hold flags onto the Salesforce account, so a rep sees an on-hold or overdue customer before promising a delivery date. The finance figures stay owned by Sage; Salesforce just reflects them read-only, so nobody edits a balance in the CRM.

### How do you handle tax codes and multi-currency between the two systems?

Salesforce is free-form and Sage is not: Sage expects a fixed tax code and nominal code on every line, and a defined currency with its own exchange-rate handling. We map Salesforce products, price books, and picklists to your Sage tax and nominal codes once, agreed with your finance team, and encode it in the pipeline. A line that cannot be mapped is held and flagged rather than posted with a wrong code.

### Who operates it after go-live?

We do. The pipeline runs on cloud-native, fully EU-hosted infrastructure that we monitor. If Salesforce retires an API version or Sage changes an endpoint, that is our problem to fix under contract, not a surprise your team finds when orders stop flowing. You get a named owner, alerting, and an SLA rather than a script somebody has to remember to run.
