Invoicing software for cleaning and facilities companies in Singapore

Most cleaning firms bill the same schedule of sites every month — offices, condos, retail units, schools — plus a handful of extras. Rebuilding those invoices in a spreadsheet each cycle burns days, and one copy-paste slip means an under-billed site nobody catches until the year-end review.

A supervisor agrees to an after-hours carpet shampoo, a post-renovation clean or an extra washroom refill over WhatsApp, the crew does it, and the paperwork stays in someone's phone. Unbilled variation work is one of the quietest ways a Singapore cleaning contract slides from profitable to break-even.

Bin liners, hand soap, floor pads, microfibre cloths and dilution chemicals move from your store to a dozen sites with no record. Without stock control per site you can't tell whether a contract is heavy on consumables or whether stock is simply walking, and you re-order the same items twice.

Supplier bills, transport claims, machine servicing and crew reimbursements arrive as loose receipts. When the GST F5 return is due, you're rebuilding output and input tax from bank statements, and you still don't have a clear per-site profit figure to decide which contracts are worth renewing.

Build each site as a customer with its agreed monthly scope and rate, then generate the whole billing run in a few clicks — monthly, quarterly or on your own cycle. Rates, GST treatment and payment terms carry forward automatically, so December's invoices match the contract you signed in January unless you change them on purpose.

Supervisors add ad-hoc jobs, materials used and hours from the mobile app while they're still on site, and those lines flow straight onto the next invoice for that customer. Nothing depends on someone remembering a WhatsApp message a fortnight later, and you can show the client exactly what was done and when.

Hold cleaning chemicals, paper goods and equipment as stock, issue them to a site or a crew, and watch levels fall in real time. Reorder points tell you when to buy before a site runs dry, and per-site consumption shows which contracts are quietly eating your margin.

Photograph a supplier bill or fuel receipt and Tallium AI's AI reads it, categorises it and files it against the right expense account with the GST captured. Output and input tax build up as you go, so preparing your GST F5 return is a review job rather than a reconstruction job — confirm current rules with IRAS or a local tax professional.
