The basics

What is sales order software?

Sales order software in many products is a fulfilment document between quote and invoice. SwiftBooks Pro does not have that document. You quote on Estimates, bill on Invoices, and tracked stock moves when the invoice posts.

If you need staged work, raise a deposit invoice then another, or invoice unbilled time from a project. Do not look for a fulfilment kanban — it is VAT invoices stay in the ledger; filing is not from here.

SwiftBooks Pro is online sales order software UK SMEs use to run a clean quote-to-cash process — from Bristol distributors and Manchester wholesalers to Edinburgh agencies and London limited companies. Every paid plan includes estimates, invoices and one-click conversion. Multi-currency invoicing is on Business and above.

Order-to-cash flow

From estimate to invoiced — without rekeying.

SwiftBooks Pro carries every customer, line item and VAT rate from the estimate onto the invoice. That is the trail. Stock on tracked products moves when the invoice posts.

FAQ

Sales order software UK — FAQs for SMEs.

Direct answers on estimates, invoices and why there is no sales-order screen.

What is sales order software?

Sales order software(sometimes called order management software) is a tool that records a confirmed customer order before the goods or services are delivered and invoiced. Many products use a sales order between quote and invoice. SwiftBooks Pro does not. Quote on Estimates, bill on Invoices. Tracked stock moves when you invoice.

What is the difference between a sales order and an invoice?

A sales order in many products is a fulfilment document between quote and invoice. This login does not have one. Sales is Estimates → Invoices. Convert an accepted estimate to a VAT invoice in one click. Tracked stock moves when the invoice posts, not when the quote is accepted.

Can I convert a sales order into an invoice in SwiftBooks Pro?

Convert the estimate instead. Sales → Estimates → convert to invoice copies customer, lines, quantities, VAT and totals onto a draft invoice. For a staged job, edit quantities on that invoice and raise another later — or invoice unbilled time from a project.

Does SwiftBooks Pro support partial and staged fulfilment?

There is no sales-order fulfilment kanban. Bill in stages with successive invoices, or convert the estimate and reduce quantities on the first invoice. Projects and timesheets cover time-based stages.

Can sales orders be linked to inventory in SwiftBooks Pro?

Estimates do not reserve stock. When you invoice a tracked product, on-hand quantity in Catalog → Inventory falls (FIFO or WAC). Low-stock flags use the product reorder level. Inventory is on Business and above.

Can I convert an approved estimate into a sales order?

No — convert it to an invoice. The live workflow is estimate → invoice. Online accept lives on the estimate portal.

Is there free sales order software for UK sole traders?

There is no free-forever plan. After a 30-day trial, Solo is £15/month ex VAT and includes estimates and invoices. Stock tracking is on Business and above. Native apps are not live — use the browser.

How does SwiftBooks Pro sales order software compare to Xero or QuickBooks?

Like Xero quotes, SwiftBooks Pro does not ship a separate sales-order document. Quote on Estimates, bill on Invoices, move stock when you invoice tracked items. That is the honest comparison — not a fake native-SO tick.
