Stop Typing Every Invoice Into Xero Twice

Raise the invoice in your job system. Open the accounts package. Type it in again. Hope the nominal code and the VAT rate match what you picked last time. Do it again for the supplier bill. Every trade business that runs a job system and a set of books does this dance, and every re-key is a chance to fat-finger a figure or drop a bill entirely.

Double entry is a tax on growth

When you are small, keying invoices into Xero or QuickBooks a second time is annoying but survivable. As the volume climbs, it becomes a real drag — and a real risk.

The cost is not only the minutes. It is the invoice that never made it across because someone was interrupted mid-entry. It is the supplier bill posted to the wrong account that turns into a clean-up job at period end. It is the fact that, because the sync happens in batches whenever someone gets to it, your books are always looking at last month — so your cash position, your VAT liability, and your outstanding debt are never quite current when you need to make a call.

None of that is an accounting problem. It is a plumbing problem: two systems that should share numbers, connected by a person retyping.

Connect the two systems once

Field Forge connects to Xero and QuickBooks Online through a secure OAuth link you authorise from your settings. No passwords are shared, and you can disconnect whenever you like.

Once it is connected, you map Field Forge to your chart of accounts and tax rates a single time. From then on, sales invoices, credit notes, and supplier bills land in the right place with the right VAT treatment automatically, instead of being coded by hand on every document.

The numbers post themselves

With the connection live, an invoice you raise in Field Forge posts across to your accounts on its own. Supplier bills captured against your purchase orders — including the ones read and matched by invoice capture — sync across too. The sync runs on a schedule, so the books stay close to current without anyone exporting a spreadsheet.

That removes the two worst failure modes in one go: nothing gets typed twice, and nothing gets forgotten because the person doing the typing got pulled onto something else.

The tax treatment carries through

For UK trades this is the part that has to be right. Field Forge calculates VAT, CIS deductions, and the domestic reverse charge on your invoices and applications for payment deterministically — and those figures are what carry through to the documents that sync to your accounts. The tax treatment stays consistent between your job records and your books, rather than being re-derived (and occasionally re-guessed) on the second entry.

And if you are not on Xero or QuickBooks

Xero and QuickBooks Online get the native connection. If you are on Sage or something else, Field Forge exports the relevant documents to CSV, and further integrations are available on request — so your data is never trapped, whatever your accountant runs.
