The catalog that makes billing fast.
Re-typing descriptions and looking up prices is where invoicing time actually goes. A good catalog deletes that work.
- ✓ Instant document lines — pick an item and the description, price and IVA 23% rate fill themselves.
- ✓ Services and goods alike — bill hours, boxes or bundles with the same speed.
- ✓ 4-decimal unit prices — totals match your price list exactly, even at volume.
- ✓ Consistent descriptions — customers see the same wording on every document.
- ✓ Sales and purchase prices — the same item works on invoices and on supplier bills.
Set up once, correct forever.
Item-level defaults are quiet insurance: the right tax and the right account, every time, without thinking.
- ✓ Per-item accounts — income and cost land exactly where your accountant expects.
- ✓ Default IVA 23% per item — zero-rated, standard or exempt, applied automatically and overridable per line.
- ✓ Bulk import — bring your existing list from a spreadsheet in minutes.
- ✓ Edit any time — price changes apply to new documents; issued invoices keep the price they were sent with.
- ✓ Used across channels — the same catalog powers manual documents and AI-drafted ones.
Items & catalog — common questions
Can I import my existing item list?
Yes — bulk import from a spreadsheet brings your whole catalog in at once, with names, prices and tax defaults.
Does it handle services as well as products?
Yes — an item can be a service, a physical good or anything you bill repeatedly; both carry prices and IVA 23% defaults.
What happens to old invoices when I change a price?
Nothing — documents keep the prices they were issued with. New documents pick up the new price.
Does OneBooks track stock levels?
OneBooks is deliberately not an inventory system: item stock fields are informational only and drive no accounting. The catalog exists to make billing fast and postings correct; if full stock control is central to your business, pair OneBooks with your POS or inventory tool.
