Why paper forms are still ordered in bulk
Most Singapore companies have moved invoicing and approvals into software, yet a surprising number still buy carbonless forms by the carton. Logistics firms hand drivers delivery order books so the customer can sign on the spot. Aircon servicing and renovation contractors fill in job sheets at the customer's flat. Warehouses use goods received notes, and workshops use service reports with a copy for the customer, a copy for the office and a copy that stays in the book. Where there is no reliable device, no signal, or a customer who wants a paper copy in hand, a pre-printed NCR form is still the fastest way to record a transaction and get a signature.
This guide covers how carbonless forms work, the choices you make when ordering them (parts, colours, numbering, binding), how to set up the artwork, and how a procurement or admin team can keep a steady supply without running out mid-month or storing boxes of an outdated design.
How NCR paper works
NCR stands for "no carbon required". Each sheet in a set is coated so that pressure from a pen on the top sheet transfers the writing to the sheets below. There are three sheet types:
- CB (coated back): the top sheet, coated on the back with micro-capsules of colourless dye.
- CFB (coated front and back): the middle sheets, which receive the image on the front and pass it on through the back.
- CF (coated front): the bottom sheet, which receives the image only.
A duplicate set is CB plus CF. A triplicate adds one CFB in the middle; a quadruplicate adds two. Beyond four parts the bottom copy becomes faint unless the writer presses hard with a ballpoint, so four parts is the practical limit for most handwritten forms.
Two practical consequences: carbonless paper is sensitive to pressure and heat, so a stack of forms stored under heavy boxes or near a hot machine can develop marks, and the transferred image fades over years in direct light. If a copy has to be kept for statutory record keeping, scan it.
Choices to make when you order
Number of parts and colours
Each part is usually a different colour so staff can tell which copy goes where without reading. A common convention is white for the customer, yellow (or pink) for accounts and blue or green for the file. Print the destination at the foot of each part ("Customer copy", "Office copy", "Book copy") so there is no guessing.
Size
A4 for invoices, statements and detailed service reports. A5 for delivery orders, receipts and job sheets that are filled in on a clipboard or the bonnet of a van. Smaller formats cost less and are easier to carry, but check the form still has room for handwriting; people write larger than they type.
Running numbers
Sequential numbering is what makes a form auditable. Tell the printer the starting number and whether each book starts on a new block (for example 1001 to 1050, 1051 to 1100). Numbers are printed in red or black on every part of the set. If different teams or vehicles each have their own series, give each a prefix (DO-A, DO-B) and ask for the books to be packed and labelled by series.
Binding and format
| Format | How it is used | Good for |
|---|---|---|
| Books of 50 sets, glued at the top or side, with a card cover | Sets are torn off; the last copy stays in the book | Delivery orders, receipts, job sheets |
| Padded sets (loose sets glued lightly at one edge) | Sets are peeled off whole and filed | Office invoices, internal forms |
| Loose collated sets | Fed into a printer or handwritten one by one | Occasional use, small volumes |
For books, ask for a writing shield: a thick card flap that slides under the set in use so the writing does not transfer onto the next set in the book. Perforations along the binding edge make tearing out clean, and a hole-punch on the file copy saves a step.
Artwork that works on a carbonless form
A form is a tool, and the design choices are about how fast someone can fill it in correctly:
- Leave boxes at least 7 mm to 8 mm high for handwriting, and wider than you think for addresses and signatures.
- Put the fields the office needs (customer name, date, number, amount, signature) in the same order as the system they are keyed into later. Data entry is much faster.
- Print your company registration number (UEN) and, if you are GST-registered, the GST registration number where invoices and receipts need them. Check the IRAS requirements for tax invoices before finalising the layout.
- Use one or two ink colours. Full colour on NCR is possible but adds cost for little benefit; a logo in one brand colour plus black text is the norm.
- Keep a clear margin at the binding edge so the glue or perforation does not cut into a field.
If several departments use similar forms, standardise them. One delivery order layout with a department code is easier to order, stock and train on than five variations. The approach in our guide to writing a print spec sheet suppliers can follow works well here: one page per form listing size, parts, colours, numbering and binding.
Keeping supply steady
Running out of delivery order books on a Monday morning stops a fleet. Running out of numbered invoice books breaks a sequence. Both are avoidable with a simple routine.
- Know the usage. Count books issued per month for each form over a quarter. That is your baseline.
- Set a reorder point. Reorder when the stock left covers the supplier's turnaround time plus two weeks. For numbered forms, include the next starting number in the order.
- Do not overbuy. A change of address, a new logo or a GST rate change can make a year's stock obsolete overnight. Six months of supply is a sensible ceiling for most forms.
- Store flat, cool and dry. Carbonless paper reacts to pressure and heat; keep cartons off the floor and out of direct sun.

When to move a form off paper
NCR forms remain the right choice where a signature is needed on the spot and devices are impractical. If a form is filled in at a desk and keyed straight into a system, it is probably time to replace it with a digital form. Many companies end up with a mix: digital invoices from the office and NCR delivery orders in the van, with the signed copy scanned back at the end of the day. Review your forms once a year and drop the ones nobody uses.
Carbonless forms from us
We print NCR forms for Singapore companies in two to four parts, A4, A5 and custom sizes, with running numbers, series prefixes, perforations, writing shields and card covers. Send us your current form (a photo of a filled-in copy is fine) and we will redraw it as print-ready artwork, check the numbering plan with you, and send a proof before production. Books can be packed and labelled per department, branch or vehicle, and reorders are repeated from the same file with the next number sequence. For other office print on the same order, see our custom printing services or the article on branded envelopes for Singapore companies. To get a quote, send your form, monthly usage and the number of parts through our contact page.
