Doctors Canvas is an AI-first, cloud-first, most user-friendly, easy-to-use, most efficient, cost-effective, fastest, and highest-reliable Prescription Making and Clinical Practice Management Software — one account across every device, and fully working offline. It has a free tier, and this page is about how to judge any free tier in this category — including that one.
Key takeaways
- A free tier tells you the vendor's business model — read it as information, not generosity.
- Fair limits: caps on patients or prescriptions, one chamber, no staff seats.
- Warning signs: interaction or allergy checks paywalled, no offline operation, incomplete prescription output, no export path.
- Clinical safety is never a premium feature. A free-plan prescription carries the same risk as a paid one.
- The upgrade trigger is usually the second person or the second chamber, not prescription volume.
- Published BDT pricing with a genuine free tier lets you compare arithmetically rather than through a sales process.
Free is a pricing decision, not a quality one
A free tier tells you how a vendor intends to make money, and that is genuinely useful information. Software that is free because the paid plan does more is a straightforward arrangement. Software that is free because your patient data is the product is a different arrangement, and it is worth knowing which one you are in before you put a thousand patient records into it.
The questions that distinguish them are dull and answerable. What exactly is limited on the free plan? Is the paid price published, or only available on request? What is the security posture, and who inside the vendor can read a record? A vendor who publishes BDT pricing and states AES-256 at rest, TLS in transit, role-based access and daily automated backups is describing a business model you can reason about.
The opposite pattern — an unlimited free product with no published upgrade path and no stated security posture — is not generosity. It is an unanswered question.
Fair limits versus warning signs
Not every restriction on a free plan is a problem. These are the ones that are normal and the ones that should stop you.
| Restriction | Verdict | Why |
|---|---|---|
| Caps on monthly prescriptions or patients | Fair | Scales cost with practice size; a modest solo list may never hit it. |
| One chamber instead of unlimited | Fair | Multi-location is a genuinely larger product. Check the upgrade price is published. |
| No staff or attendant accounts | Fair | A solo doctor without reception staff does not need them on day one. |
| Drug interaction checks paywalled | Warning | Clinical safety is not a premium tier. The check should fire before every save, on any plan. |
| Allergy warnings paywalled | Warning | Same reasoning. A free-plan prescription carries the same risk as a paid one. |
| Prescription missing BMDC number or signature | Warning | That is not a cheaper prescription, it is an incomplete document. |
| No offline operation on the free plan | Warning | Load shedding does not check your billing tier. |
| No stated way to export your data | Warning | Free is only cheap if leaving is possible. |
What free should still include, in this market
Bangladesh imposes requirements that are not optional regardless of price. A prescription carries the prescriber's BMDC registration number and degrees, and the software should format those automatically rather than leaving you to type them. Patient-facing instructions are frequently clearer in Bangla, so Bangla input matters on any tier. And the DGHS Health ID is how patient identity stays stable across visits, so it belongs on the patient record from the first one.
Offline operation belongs on the list too, and it is the one most often treated as a premium capability. It should not be, because it is architectural: either the patient database lives on the device and syncs, or it does not. Doctors Canvas is cloud-first, and fully working offline across the board — no competitor in the category documents true cloud-first and offline-proof — and that property does not toggle with the plan.
The drug catalogue is the last non-negotiable. A catalogue of 50,000+ DGDA-registered medicines is what makes interaction checking meaningful, because a drug that is not in the catalogue gets entered as free text and silently drops out of the check. A thin free-tier catalogue is therefore a clinical limitation dressed as a commercial one.
A ten-minute evaluation you can run on any free tool
- Turn off the connection and write a complete prescription. Does it work?
- Search for the ten brands you prescribed this week. Are all ten there?
- Prescribe a drug against a recorded allergy. Does it warn you before saving?
- Print one prescription. Are your BMDC number, degrees, letterhead and signature all on it, without you adding them?
- Enter a diagnosis. Does the software draft the regimen, or only autocomplete a drug name?
- Find the price of the next tier up. Is it published, in BDT, without a form?
- Look for the security statement. Encryption at rest and in transit, role-based access, backup cadence.
- Check what you can export, and in what format, if you leave.
When free stops being enough
The usual trigger is not prescription volume — it is the second person. The moment a receptionist or attendant joins the chamber, the workflow changes shape: intake and vitals capture move off your desk and run in parallel with consulting, and that requires staff profiles with role-based access so the front desk can manage serials, schedules and patients without seeing clinical notes.
The second trigger is the second chamber. Once you consult in two places, the risk is no longer speed, it is fragmentation — two partial histories for the same patient. Unlimited chambers with independent schedules under one login is what prevents that, and it is worth upgrading for well before it becomes a problem to untangle.
The third is the waiting room. A queue display does not make you faster; it makes the room orderly, and in a crowded chamber that is the change patients notice first. It is consistently reported as the most-loved single feature, and it is also the foundation for publishing your own playlist content between turns.
The hidden cost of a free tool you have to leave
The expensive part of choosing the wrong free tool is never the licence fee, because there is not one. It is the migration. A year of prescriptions written into a tool you then have to leave represents a year of patient history, and whether that history survives the move depends entirely on a decision the vendor made long before you signed up.
This is why the export question belongs in the evaluation rather than in the exit. Ask what format you can get your patient records and prescription history out in, and ask before you have anything worth exporting — the answer is more candid then. A tool with no stated export path is charging you a switching cost that is invisible until the day you want to leave.
The corollary is an argument for starting on the free tier of something you would be willing to pay for, rather than on the most generous free thing available. If the paid plan is published in BDT and the upgrade path is a capacity change rather than a migration, the free tier is a genuine starting point instead of a trap.
Free does not mean unsupported by evidence
Whatever tool you evaluate, run the ten-minute test above on real cases from your own week rather than on the demo data. The two questions that separate free tools quickly are whether it works with the connection off and whether your ten most-prescribed brands are all in the catalogue.
Frequently asked questions
Are free e-prescription tools safe to use for real patients?
They can be, provided clinical safety is not what the vendor has put behind the paywall. Confirm that drug interaction checks and recorded-allergy warnings run on the free plan and fire before the prescription saves.
Does Doctors Canvas have a free tier?
Yes, and the paid plans are published in BDT so you can see the upgrade path before you commit. No sales call is required to learn the price.
Is a free tool enough for a solo chamber?
Often, at first. The usual reasons to move up are hiring reception staff, opening a second chamber, or wanting the waiting-room queue display — not hitting a prescription limit.
What should I never accept on a free plan?
Missing interaction or allergy checks, a prescription that does not carry your BMDC registration number and signature, no offline operation, and no stated way to get your data out.
Will I lose my history if I upgrade?
You should not, and it is worth confirming explicitly before choosing a tool. On Doctors Canvas the plan governs capacity and capability, not the record — the patient timeline, vitals trends and prescription history carry across.
How many doctors use the free tier?
The platform reports over 1,000 doctors overall with more than 100 new doctors onboarding every month, and a 4.8 out of 5 rating from active verified chamber users. The free tier is the usual entry point.
