A freelance invoice app is a secure online platform where freelancers can manage all their invoicing needs in one place. You can create, send, and track invoices for your clients, as well as keep an organized record of payments and outstanding balances. This helps streamline your workflow and ensures you always have access to your financial info, without the need for spreadsheets or manual tracking.
Softr makes it simple to build a freelance invoice app that fits how you work. You can connect your existing data—like project details in Airtable, payment records in Notion, or client info in HubSpot—and set up an app where you can generate, send, and manage invoices for all your freelance projects in one easy place.
You don’t need any coding experience. Start with a template or build from scratch, customize your layout, decide what information is visible for each client, and brand it to match your freelance business. It’s quick to launch, easy to maintain, and flexible enough to grow as your freelancing evolves.
You can include a variety of useful features in your freelance invoice app, depending on your workflow. Common options include:
\- User logins – so you and your clients can securely access invoice details
\- Custom dashboards – to track paid and outstanding invoices, project statuses, or total earnings
\- Invoice generation – quickly create and send professional invoices
\- Payment tracking – record payments and see outstanding balances
\- File sharing – upload receipts or supporting documents for each project
\- Search and filters – easily find invoices by client, date, or status
\- Tables and detail views – display lists of invoices, payment history, or client info
\- Comments or status updates – keep a record of communication around each invoice
\- Charts – visualize income trends, overdue payments, or project breakdowns
\- Permissions and roles – so clients only see their own invoices and info
All features are set up using Softr’s drag-and-drop blocks, so nothing requires coding. As your freelance business grows, you can easily update your app to match your needs.
No coding is necessary. You can build your entire freelance invoice app using Softr’s visual editor. From the layout to user access controls, everything can be customized without writing a single line of code.
Yes. You can manage invoices for multiple clients or teams within the same freelance invoice app. Each client or team member only sees the invoices and billing information assigned to them, based on their login and permissions. This is ideal for freelancers who juggle projects across several clients, or agencies handling invoicing for different groups.
Softr supports a wide variety of data sources for your freelance invoice app. You can connect to Airtable, Google Sheets, Notion, Coda, monday.com, HubSpot, Clickup, Xano, Supabase, PostgreSQL, MySQL, SQL Server, MariaDB, BigQuery, and more. If you use another tool, you can also bring in data via the REST API.
You're not limited to just one data source. For example, your freelance invoice app can pull in invoice records from Airtable and client contact details from HubSpot simultaneously. Most integrations support real-time, two-way sync so updates stay in sync automatically.
Yes, Softr gives you complete control over the user experience in your freelance invoice app. You can adjust the layout, navigation, and dashboard to match your workflow and branding. Each section or page can be shown or hidden depending on who's logged in, so clients only see their own invoices and payment history.
You can also set up different user roles—like client, freelancer, or admin—so that each role has access only to the features and data they need. For example, clients can only view and pay their own invoices, while you or your team can manage all client billing records. Customizing permissions in this way keeps your freelance invoice app organized, secure, and tailored for each user.
Yes, you can. You don’t need to import data from another platform to start building your freelance invoice app with Softr. If you’re starting from scratch, you can use Softr Databases, which are built right in and work seamlessly with your invoice workflows.
If you already have client or invoice data in tools like Airtable, Google Sheets, HubSpot, Notion, Coda, monday.com, Supabase, or SQL, you can connect those as well. You can even use the REST API connector to bring in data from other sources. This gives you full flexibility over how your client and invoice data is structured in your app.
Yes, you can fully white-label your freelance invoice app in Softr. You can use your own logo, brand colors, fonts, and custom domain to make the app feel like an extension of your freelance business. You can also remove all Softr branding, so clients only see your branding throughout their invoicing experience.
Yes, you can. Softr gives you a lot of flexibility to control both the design and layout of your freelance invoice app. You can adjust colors, fonts, spacing, and page structure to match your freelance brand. You can also choose how each page is laid out, decide which blocks go where, and set what different users see when they log in.
To display your data, you can add different types of blocks depending on what you need:
\- Table blocks – to show structured data like invoice lists, payment records, or project overviews
\- List or Card blocks – to highlight things like client profiles or outstanding invoices
\- Detail View – to show one invoice or project at a time
\- Forms – for submitting invoice details or payment info
\- Charts – to show financial summaries
\- Calendar blocks – to display invoice due dates or payment schedules
If your content or design needs change later, it’s easy to go back and make updates right in the visual builder.
Softr is built with security in mind. All data is encrypted in transit (TLS) and at rest, and your apps are hosted on secure, reliable infrastructure. Softr apps give you full control over who can see and do what with your freelance invoice app. You can set up role-based permissions, manage users directly within your data source, set visibility rules, and apply global restrictions to protect sensitive data across your entire app.
For apps connected to external data sources like Airtable, Notion, or SQL, Softr doesn’t store your data—it just displays it in real time based on your access settings. You’re always in control of your invoice data and who can view or edit it.
Softr also follows industry best practices for authentication, access control, and platform monitoring to help keep your information safe.
You can get started for free. Softr’s Free plan lets you publish one app with up to 10 app users and 2 user groups, and includes support for all standard data sources like Softr Databases, Airtable, Google Sheets, and more.
If your freelance invoice app needs more users or features, you can upgrade to a paid plan as your needs grow. You can check the latest pricing details here: <https://softr.io/pricing>
Softr is built to make it easy to create fully functional, user-facing apps—like freelance invoice apps, client portals, and internal tools—without needing to write code or rely on developers. What sets it apart is how quickly you can go from idea to a working app, and how seamlessly it connects with your existing data.
Unlike some no-code tools that focus on mobile apps (like Glide) or are geared towards developers (like Retool), Softr is designed for freelancers and non-technical users who want full control over layout, user experience, and permissions. You can build on top of real-time data from tools like Airtable, Google Sheets, Softr Databases, or SQL, and create branded, secure apps for managing invoices and payments.
Everything is customizable visually—from design to user roles. Plus, with built-in features like forms, conditional logic, and API support, you don’t need to piece together multiple tools to launch a professional freelance invoice app.
Yes. Softr supports a wide range of integrations so you can connect your freelance invoice app to the rest of your workflow. You can sync with tools like Stripe for payments, automate reminders or notifications using Zapier, Make, or N8N, and connect to CRM or accounting tools as needed. Softr also supports REST API and webhooks for more advanced automations.
Whether you want to send invoice data to your accounting software, trigger emails when invoices are paid, or display real-time payment data from other tools, you can build these workflows right into your freelance invoice app—no coding required.
