Estimating software vs Excel for industrial contractors
A spreadsheet is free the way an uninsured bakkie is free.
Excel is where most contractors start, and for a while it's fine. Here's exactly where it stops, and what an estimating catalogue does that a workbook can't.
When Excel spreadsheets are fine for estimating
- You're on your own and quote a handful of jobs a month.
- The jobs are simple: a few lines, no crews, no difficulty factors.
- One person owns the sheet, and only that person ever touches a rate.
- You've never had a client query a price you couldn't reconstruct.
If that's you, keep your spreadsheet. The moment a second estimator, a revision, or a margin dispute enters the picture, read on.
7 ways spreadsheets break for contractor job costing
Silent formula errors
A dragged formula stops one row short, a #REF! hides inside a rolled-up total, and the job is priced wrong before anyone looks at it. There's no warning - just a number that's quietly out.
No price snapshots
The workbook you edit is the record you destroy. Change a rate today and last month's "sent" quote silently changes with it: there is no frozen copy of the figures the client actually saw.
No roles
Anyone with the file can change any rate or markup, and nothing records who did. Consistency depends on everyone being careful, forever.
Versioning by filename
quotes_FINAL_v7 (3).xlsx. Which one did the client accept? Nobody's certain, and the answer matters when the money's disputed.
No consolidated products list
Every product is scattered across tabs and tasks; someone re-keys them into a buy-list by hand, and misses one.
A shared job has no shared home
When three companies price one job, the numbers travel by email and WhatsApp and get retyped into a master workbook. One digit slips - R203 500 becomes R230 500 - and the error ships to the client with nobody's name on it.
The job's cost lives in another workbook
What the job was priced at sits in one sheet, what it cost in another, what was invoiced in a third - and the retention in someone's head. Nobody adds them up until year-end, and by then the next job has been priced the same way.
A spreadsheet does not know what you sent the client six weeks ago.
Feature comparison: Excel vs Quotier estimating software
The same estimating job, two tools.
| Excel | Quotier | |
|---|---|---|
| Rates & markups | In cells, copied into every new quote | One catalogue, reused on every quote |
| Standard crews | Retyped each time | Saved on the action, seeded automatically |
| Difficulty pricing | A manual multiplier, easily missed | A factor applied to labour on every quote |
| Sent-price snapshots | None: editing overwrites the record | Frozen the moment you send |
| Revision record | A new filename, and hope | Numbered revisions, originals kept |
| Acceptance record | An email, somewhere | Recorded against the client's order number, with timestamps |
| Invoice from the quote | Rebuild it by hand | Deposit / progress / final off the agreed total |
| Products buy-list | Copy-paste across tabs | One consolidated buy-list, rolled up |
| Who can change a rate | Anyone with the file | Owners & admins set the book; estimators can't |
| Does the PDF always add up | Depends on the last edit | Rounded per line, sums to the cent |
| Several companies on one job | Emailed sheets, retyped into a master | Each company quotes its share; totals roll up at the level each chooses |
| Retention | A note in the terms, chased from memory | Withheld per draw, released by invoice, defects period tracked |
| Part-payments | Overwrite the "paid" cell | Each receipt recorded; the remainder is what's owed |
| Job cost vs quote | A separate workbook, if at all | Expected · Actual · Variance on the job |
| Supplier orders | An email, quoted from memory | Numbered POs, goods received, matched to the invoice |
| Month-end | Export and retype | One pack with every document - plus a VAT201 working paper for SA vendors |
Transitioning your rate sheets from Excel to Quotier
The switching cost is smaller than it looks. You already have your rates - they're in the sheet. Setting up the catalogue is an afternoon: labour types and hourly rates, products with their cost and markup, and your standard actions with their crews.
After that, you don't rebuild anything. Every quote pulls from the catalogue, every sent price is frozen, and every revision is on record. The spreadsheet was free to start and expensive to keep; the catalogue is the opposite.
Jobs already in flight come with you. Record the quote, invoice or order you issued before Quotier against the job - with its own number and date - and the ledger, the statement and the VAT working paper see it. Quotier mints no PDF for it: the customer already holds the real one.
Do the maths
Miss a 20% markup on R150 000 of products in a spreadsheet and R30 000 is gone - about a year of Quotier. Quotier applies the markup on every line because it lives on the product, not in someone's memory.
Quotier vs Excel: common questions
Can I import my existing spreadsheet?
Not as a bulk upload: you set the catalogue up once by entering your labour types, products and standard actions. It's usually an afternoon, and it's the last time you re-enter a rate, because every quote after that pulls from it.
Is it free to see if it beats my spreadsheet?
Yes. The free plan gives you 15 quotes a month, up to 5 lines each, with one user, enough to price real jobs against your sheet. It's a free plan, not a trial; nothing expires.
What actually stops working in Excel first?
Usually the second estimator, or the first disputed price. The moment more than one person prices work, or a client queries what they were sent six weeks ago, a workbook can't give you a consistent number or a frozen record. A catalogue does both.
We have retention and part-payments on jobs right now - can those move?
Yes. Record the invoices you've already issued against the job, then record the payments received against each. From there the job bills and chases like one that started in Quotier. Retention withheld on invoices issued before Quotier isn't on the ledger - only draws issued from Quotier feed the release - so release the figure your own records hold.
