Airtable suits structured data and working views; Notion suits work that combines documents and data. A custom platform becomes an option when a process has requirements you can’t handle or maintain well in the chosen tool. Headcount alone doesn’t decide that. First establish where the current work gets stuck.
Our custom software guide covers the wider decision. For process automation, read no-code or custom work and connecting software.
What are you comparing with Airtable and Notion?
You’re comparing an existing product with software configured or built for your process. An existing product operates within the vendor’s features and terms. With custom work, you agree which features will be built and also fund development and maintenance.
Notion describes databases as collections of pages, with properties and different views. A project file containing written context is a different use from continuous order processing. Focus on the central task, rather than which tool can do the most in general.
Which route suits which work?
| Need | Candidate to test | Deciding check |
|---|---|---|
| Manage structured records | Airtable or a similar data tool | Relationships, validation and daily edits |
| Connect knowledge and project documents | Notion or a similar document tool | Search, structure and access |
| Combine a document with calculations and actions | Include Coda in the trial | Maintaining formulas and connected functions |
| Support an unusual process with distinct user roles | Existing product, custom work or a combination | Whether the complete process works |
Product documentation checked on 2026-09-24. This is a starting point for a trial, not a ranking. A well-configured product can work better than a poorly specified custom platform. Equally, a small custom function may remove manual work without replacing the document environment.
When do you reach limits?
Record count alone doesn’t predict slowness. Relationships, formulas and concurrent work matter. Airtable documents an API limit of five requests per second per base. That’s an integration limit, not an interface performance benchmark. Source checked on 2026-09-24.
Test a busy process with representative data. Run an import while employees edit the same records, for example. Record waiting time, errors and recovery work. If results disappoint, investigate the cause first: a poor design can make custom software slow too.
How do you assess permissions and customer access?
List what each role may read and change. Test separate accounts and try opening information that should be hidden from each role. A filtered view is suitable only when access rules actually protect the underlying data.
Notion documents several sharing and permission settings. Check what’s available in your plan and setup. Ask for the same demonstration in Airtable and a custom platform. Custom software doesn’t automatically separate customer data properly; that needs design and testing.
How do you compare total costs?
Obtain current rates for the roles and features you need. Get a custom quote for the same scope, then include setup, migration and maintenance. Comparing a licence fee with a server bill isn’t useful.
Include remaining manual work. Ask employees to record the time a recurring workaround actually takes. That reduces reliance on optimistic estimates. Don’t assume custom software removes every workaround: have the proposed solution demonstrate it.
Choose a comparison period that fits your plans and include growth. More users, more data or a customer portal can create different costs. There is no fixed headcount above which custom software is always cheaper.
When does a combination help?
Suppose a training company keeps scheduling and participants in Airtable but produces certificates elsewhere. This is a hypothetical example, not a TopDevs client case. First assess whether a document function solves the missing step. Scheduling and participant management may not need to move.
Agree which system is the source for each record. If a participant changes, the team must know where that change starts and how other systems receive it. Otherwise, several conflicting versions can develop.
For an existing project, see the Mastone case study. Use a case to identify questions for your process, not as proof that the same solution or price suits every business.
How do you test whether a switch is needed?
Have a user perform the same daily action in the candidate solutions. Include an exception, such as a duplicate request or missing field, and assess the explanation and recovery needed.
| Trial | What should you record? |
|---|---|
| Enter and edit data | Steps, checks and duplicate entry |
| Open the busiest view | Waiting time under agreed test conditions |
| Interrupt an integration | Error visibility and recovery procedure |
| Export data | Available fields, relationships and attachments |
Agree the acceptable outcome first. Otherwise, a demonstration becomes a comparison of attractive screens. Ask the future maintainer to make a change too. A solution only its developer understands can demand considerable support later.
How do you prepare a migration?
Inventory tables, documents, relationships and automations. Check what exports actually contain; attachments and history may require separate work. Run a trial import and compare it with the source.
Then plan the transition. Who can still edit during the final transfer? How will changes made during testing be handled? When would you roll back? The answers determine the approach and duration. A fixed promise of a few weeks means little without this assessment.
Agree handover and maintenance for custom software. The code remains yours; rights to third-party products and components apply separately. Read code ownership and vendor lock-in for the terms to check.
How do you actually get started?
Describe the main process and choose one problem. Test whether the existing tool can solve it. Then compare an improvement, a combined approach and full replacement against the same requirements and total costs.
