1. The short answer
Excel is brilliant at a lot of things, and it's already on your computer. For a budget, a quick calculation or a one-off list, nothing beats a blank spreadsheet.
But a construction program isn't a one-off — it changes every week. That's where a spreadsheet starts to cost you: every slip means dragging dates by hand, there's no baseline to measure against, and the "latest version" is whoever's inbox. SiteCal does the construction program the way a spreadsheet can't — and keeps one live copy everyone can see.
- A program that actually changes
- Keeping the schedule true without the busywork
- Sharing one live copy with every trade
- Budgets, quick sums and one-off lists
- A program that never moves
- Total flexibility, with no new tools
2. What each tool is built for
Excel is a general-purpose spreadsheet — a blank grid you can bend to almost anything, which is exactly why builders reach for it. It'll draw a Gantt chart and hold a list of dates. What it won't do is understand that those dates depend on each other.
SiteCal is built for one thing: the construction program. It knows a task is start-plus-duration in working days, that trades follow one another, and that moving one should offer to move the rest. You get links and cascade, a locked baseline with ahead/behind tracking, trade colours, a month calendar, and a live link for every trade and client.
A spreadsheet holds your dates. SiteCal understands them — and tells you the moment the job starts to slip.
3. Feature comparison
For a program that lives on site and changes as the job moves. Ticks mean it does the job well; half marks mean it's possible, but manual or clunky.
4. When a task slips
This is the moment a spreadsheet shows its seams. Rain puts the frame back three days, and every trade behind it has to move. Here's the same change in each.
- Open the spreadsheetFind the frame row among everything else.
- Push the frame out three daysDrag or retype its start and finish.
- Move every following tradeLock-up, fit-off, the lot — by hand.
- Fix what you missedThe task you forgot, and the weekend you didn't skip.
- Save a new version and email itAnd hope everyone opens the right one.
- Move the taskFrom your phone on site or your laptop in the office.
- Confirm the shiftThe whole chain moves, and every trade's link already shows it.
5. One version, or ten
A spreadsheet travels as a file. You email it, someone saves a copy, you make a change, you email it again — and within a week there are three "final" versions and nobody's sure which is live. The trades working off last Tuesday's copy turn up on the wrong day, and you field the phone calls.
SiteCal keeps one copy. You share a read-only link, and when you move a task everyone looking at that link sees the new dates. No attachments, no versions, no "which one's current?".
6. What Excel still does better
This isn't a case against spreadsheets. Excel is the right tool a lot of the time:
- Cost. It's already on the computer, or a few dollars a month as part of Microsoft 365. SiteCal is from $89/month.
- Familiarity. Everyone can open a spreadsheet and find their way around it.
- Flexibility. A blank grid does anything — budgets, quick sums, a one-off list. SiteCal only does the program.
- Offline. A local spreadsheet works with no internet at all.
The honest line: keep Excel for the things a spreadsheet is great at. It's the living program — the one that changes every week and has to reach every trade — where it starts costing you more than it saves.
7. The verdict
Choose SiteCal if…
- Your program changes — and it always does
- You want it to keep itself straight when a task moves
- You want trades working from one live copy
- You want a baseline, so you can see the slip
Stick with Excel if…
- Your program genuinely never moves
- You don't want to add a new tool
- You need a spreadsheet's flexibility for everything else

For most builders the program is a living thing — it moves the week it starts, and it has to reach every trade. That's the job SiteCal was built for. Keep the spreadsheet for the budget.
