Xero to Postgres integration for a queryable accounting replica

The Xero to Postgres integration from Adapters syncs invoices, contacts, payments, and the chart of accounts from the Xero Accounting API into your own Postgres tables on an incremental schedule, so finance reporting and internal apps query ledger data with plain SQL instead of paging the Xero API. Field mapping takes about a minute and no code is required.

What running Xero to Postgres by hand costs you

Xero reports cannot join to your product, CRM, or billing tables, so questions that span accounting and app data get answered by exporting to a spreadsheet.
The Xero API caps you at 60 calls a minute and 5,000 a day per org, so a live lookup from your own application is slow and rate limited.
Invoices and payments change after they post, and a one-time CSV export into Postgres is out of date before the next reconciliation.

The field mapping, out of the box

These cables are pre-wired when you pick the pair. Rewire any of them, or add your own, in the same visual data mapping tool you use for every adapter.

Transforms included

Incremental loads use the Xero UpdatedDateUTC watermark plus the If-Modified-Since header so only changed records come back and you stay under the rate limit; amounts cast to Postgres NUMERIC(19,4), the nested Contact object flattens to a foreign-key column that joins the contacts table, the Microsoft-format date strings parse to TIMESTAMPTZ in UTC, and writes upsert with ON CONFLICT on the Xero object id so a retry never double-inserts.

How it goes live

Three steps, minutes end to end, covered by flat data integration pricing from $49 a month.

STEP 01

Pick the pair

Connect Xero and Postgres with scoped credentials. About a minute each.

STEP 02

Confirm the mapping

The cables above are pre-wired. Adjust any field, preview the transform on sample records, done.

STEP 03

Schedule the sync

Hourly down to every minute, with retries, alerting, and a full log on every run.

Xero to Postgres sync: common questions

How does the Xero to Postgres sync work?

How much does the Xero Postgres integration cost?

Pricing is flat and monthly: Starter at $49, Growth at $149, Scale at $399. Every plan includes this pair, visual field mapping, and per-record logs. There are no per-task or per-row fees, so the bill stays the same as volume grows.

How often can Adapters sync Xero to Postgres?

Hourly on Starter, every 5 minutes on Growth, and down to every minute on Scale. Failed records retry automatically with backoff, and alerting plus a full per-record log come standard on every run.

Do I need to write code to connect Xero and Postgres?

No. Fields are auto-mapped the moment you pick the pair, and you can rewire any mapping visually before the first sync. Incremental loads use the Xero UpdatedDateUTC watermark plus the If-Modified-Since header so only changed records come back and you stay under the rate limit; amounts cast to Postgres NUMERIC(19,4), the nested Contact object flattens to a foreign-key column that joins the contacts table, the Microsoft-format date strings parse to TIMESTAMPTZ in UTC, and writes upsert with ON CONFLICT on the Xero object id so a retry never double-inserts.
