1. Trying to attach a credit-card job to an invoice
✕
Don'tSet a job's payment method to Credit Card and try to attach it to an invoice — it won't be offered.
✓
DoSet the payment method to Invoice from the start if you'll ever bundle it, add materials, or send a pay-link. Card jobs are self-contained.
2. Using a manual line for a service in your catalog
✕
Don'tType "Mowing — $50" as a manual invoice line when "Mowing" is in your catalog.
✓
DoCreate a job with the catalog service — it shows in the Services report, the catalog price applies, and your reports stay consistent. Manual lines are for things that aren't services — materials, permits, fees.
3. Editing a job after the invoice has been opened
✕
Don'tTry to change a job's price or service after attaching it to an open invoice.
✓
DoEdit the invoice line directly, or void the invoice (which releases the job) and rebuild.
4. Voiding a partially or fully paid invoice
✕
Don'tTry to void an invoice that already has a payment recorded — even a partial one.
✓
DoRefund first and then void, or write it off as bad debt. Void is only for invoices with zero payment received.
5. Mixing payment methods on jobs you plan to bundle
✕
Don'tSet some recurring jobs to Credit Card and others to Invoice if you want them on one bill — card jobs charge separately and never appear on the bundle.
✓
DoPick one payment method per customer / contract and stick with it.
6. Expecting Revenue, Collected, and Services to be the same number
✕
Don'tTreat the totals as cross-checks; they use different sources.
✓
DoRead them for what they are: Revenue = billed amount of completed work (by scheduled date); Collected = cash received (by paid date); Services = catalog-service breakdown of that work. Manual invoice lines count toward Collected but not the other three, so heavy manual-line use widens the gap — expected, not a bug.
