Buying a mobile app in Canada means buying across several time zones
A national search for mobile app developers produces a list that spans a continent, and the practical difference between two otherwise equal suppliers is often nothing more than when their working day overlaps with yours. Half a working day of overlap is enough for a well specified build with weekly checkpoints. It is not enough when the product is still being defined and decisions are needed hourly, which is exactly the phase most projects underestimate.
So decide early which kind of engagement you are running. If the requirement is stable, distance costs you very little and widens the field considerably. If you are still discovering the product, prioritise overlap and a named person who is reachable during your afternoon. Ask each supplier to state their core hours in the proposal rather than assuming a shared clock, and ask who answers when the person you have been talking to is offline.
Bilingual is an architecture decision, not a late translation pass
If your users include French speakers, and in this country that assumption is safer than the reverse, language support has to be designed in from the first sprint. That means the interface pulls every string from a resource file rather than hard coding text, that layouts survive strings which grow when translated, that dates, numbers and currency follow the user's locale, and that notifications, error messages and emails sent by the backend are covered too. Retrofitting this into a finished mobile app is one of the most reliably expensive corrections in the business.
Language obligations are stronger in Quebec than elsewhere, and they reach consumer facing software, contracts and support material rather than just marketing copy. Whatever your legal position, name it in the brief. Then decide who supplies and reviews translations, because a supplier that runs strings through a machine and ships them will produce an interface that reads as foreign to exactly the audience you were trying to reach.
Privacy and consent reach the app, and the store listing states them
Federal privacy law applies to commercial handling of personal information, provinces add their own rules, and health data brings its own regime again. Inside a mobile app this is not an abstract compliance exercise. Location, contacts, camera, microphone, health data, advertising identifiers and analytics each need a reason, a permission prompt at a sensible moment, and an entry in the privacy disclosures both stores require you to publish.
Those disclosures are a commitment, and a mismatch between what your listing declares and what the code actually collects is a rejection risk at review time and a credibility risk afterwards. Ask suppliers which third party components they intend to include and what each one transmits. Advertising, attribution and crash reporting libraries are the usual surprises. Ask for the list before the build, not at submission.
Accessibility expectations now apply to software, not only to buildings
Accessible service requirements have been tightening across provinces, and public sector procurement will usually ask directly. For a mobile app the practical items are screen reader labelling on every control, support for enlarged system text without breaking layouts, sufficient colour contrast, touch targets that work for imprecise taps, and interaction that does not depend on a gesture alone.
These are cheap when designed in and tedious when added later, which is why they should appear in the brief as requirements rather than as a wish. Ask how the supplier tests them, and ask to see a prior product operated with a screen reader. Anyone who has done the work can show you in minutes. Anyone who has not will describe an intention.
Contracting, currency and who carries the estimating risk
Fixed price transfers estimating risk to the supplier and is reasonable when the product is a known shape. It punishes both sides when the requirement is exploratory, because the supplier pads and you pay for the padding. A dedicated team arrangement suits products that will keep changing, which is most of them, but it puts the sequencing decisions on you and needs a cap and a review point to stay honest.
For cross border buyers the practical items are the billing currency, which sales taxes apply, and whether payments are held anywhere in the chain. For everyone, the clauses that matter most on mobile app work are ownership of source code and design files on payment, a perpetual licence to any reusable component the supplier brings, custody of the signing keys and store accounts, and a defined exit with a handover package and a rate for transition support. Agree the exit while everyone is still enthusiastic.
What belongs in the request before anyone quotes
Describe the task the mobile app performs for the person holding the phone, in plain language, before listing features. Name every system it must connect to and who controls each one, since dependence on an interface you do not own is the most common reason a launch date moves. State which platforms are required at launch instead of assuming both. Say what data you hold and where it may be stored. Say what you would still want to own if the project stopped halfway.
Then say what you are not asking for. Without a boundary, every supplier guesses differently and you end up comparing imaginations. To see the range of firms working on this before you write anything, start from the wider mobile app development directory, and if the same programme also needs backend or platform work, look separately at software engineering firms working nationally.
Turning a national longlist into three real conversations
Three suppliers is the right number. Brief them identically, in writing, and share any clarification with all of them. Ask each for the same artefact: approach, named team, assumptions, exclusions and what they consider the riskiest part of the requirement. The differences will be visible immediately, and the supplier who names a risk you had not considered is usually the one who has done this before.
Then check operations rather than portfolios. Ask for a live product, look at how often it has been updated, read its recent reviews and see whether anyone answered them. When your requirement is written and you want several verified mobile app companies answering the same questions at once, request comparable proposals and judge the replies against the brief rather than against each other's confidence.
