What a good quotation contains
A quotation is a promise. When it is clear, the customer knows exactly what they are buying, what it will cost and what is not included; when it is vague, every gap becomes an argument later. The quotations that get accepted quickly in India tend to share the same anatomy:
- Who and when. Your legal name and GSTIN, the customer's name, a quotation number, the date and a validity period.
- Itemised lines. Each item with a quantity, a unit (nos, sqft, kW, hour, visit) and a rate, so the customer can see how the total is built.
- Tax shown correctly. The GST slab per item and the CGST/SGST or IGST split, with the taxable value and total on separate lines.
- Scope and exclusions. What you will do, what you assume, and what you will not do. This is where disputes are prevented.
- Payment milestones. Advance, stage payments and final payment, as percentages that add up to 100.
- Warranty and terms. Plain sentences, not legal boilerplate.
Proposora's quotation maker is built around that anatomy. The sections are there by default for every industry template, with realistic wording you edit rather than a blank box. See the full list on the templates page.
Why the maths matters more than the design
Most quotation tools treat the total as a sum of rows in a spreadsheet. That breaks down the moment you add a document-level discount, mix GST slabs, or round off to the rupee: the printed figures stop adding up and the customer notices before you do. Proposora computes everything through a single pricing engine with deterministic rounding. Each line is rounded, totals are sums of rounded lines, document discounts are allocated across lines so the tax breakdown stays exact, and an optional round-off is shown as its own line. The same engine renders the PDF, the share page and the invoice, so they can never disagree.
Quotation, estimate, proposal or invoice?
People use these words loosely, and Proposora handles all four without making you choose a different product. An estimate is a rough figure you refine. A quotation is a firm offer. A proposal is a quotation with a narrative around it: executive summary, approach, schedule, assumptions. An invoice is what you raise after acceptance, and in Proposora it is created from the accepted quotation with one click so the numbers carry over exactly.
Who uses the quotation maker
Electrical and solar installers quoting point-wise or per kW; HVAC and fabrication contractors quoting by unit and weight; civil contractors quoting by square foot with budget rates for tiles and fittings; agencies and consultants quoting retainers and phases; freelancers quoting a fixed scope with revisions. Each has a dedicated starter template and, where it helps, a dedicated page: see electrical, solar and contractors.
