Setup guide

The 5-minute setup

From signup to your first automatically booked invoice. Each step is a screen in the setup wizard — this guide walks through what to expect and what to have ready.

1
Create your account
Sign up at app.booksyncer.com. No card required to start on the Free plan.
2
Connect Stripe
Authorize BookSyncer through Stripe Connect — read-only access, one click.
3
Connect e-conomic
Authorize BookSyncer in your e-conomic agreement via the app grant flow.
4
Pick your accounts
Choose the journal, debtor, clearing, fee, FX and bank accounts from live dropdowns.
5
Review VAT & go live
Confirm VAT rules, run a test on your last invoice, then enable sync.

1. Create your account

Sign up at app.booksyncer.com with your work email. You start on the Free plan, which syncs up to 25 events per month — enough to try the whole flow end to end before you decide to upgrade.

2. Connect Stripe

Click Connect Stripe. You'll be taken to Stripe to authorize BookSyncer through Stripe Connect. We request read-only access to your invoices, charges, refunds and payouts — nothing that can move money. Because events arrive on a single platform webhook, there is nothing to configure inside Stripe.

3. Connect e-conomic

Click Connect e-conomic. You'll be redirected to e-conomic's official grant screen, where you approve BookSyncer for your agreement. e-conomic sends back an agreement grant token, which we encrypt and store. We never see your e-conomic login.

4. Pick your accounts

BookSyncer reads your e-conomic agreement and presents live dropdowns so you can map the following:

  • Journal for Stripe entries
  • Debtor (accounts receivable) account for customer payments
  • Stripe clearing/balance account
  • Stripe fee account
  • FX gain/loss accounts
  • Bank account for payouts
  • Optional: customer group, payment terms, invoice layout(s), product mappings

5. Review VAT rules and go live

BookSyncer proposes VAT zones and codes based on your e-conomic setup. Review them, adjust any overrides, then run a test on your last invoice — a dry-run preview that shows exactly what would be booked without touching your ledger. When it looks right, enable sync.

You can also set a historical start date here if you want BookSyncer to catch up on invoices from an earlier point, and choose auto-book or draft-only behavior.

That's it

From here on, BookSyncer books your Stripe activity in e-conomic automatically. Head to the dashboard to watch events flow in, and use the drill-down view to see exactly what was posted for each one.
