Every Tool You Need to Run a Modern Curtain and Blind Business
InterioApp was built from the ground up for made-to-measure retailers. Here is what five years of focused development has produced - and what it means for your business today.
Most software built for window furnishing retailers was never actually built for window furnishing retailers. It was adapted - a generic job management tool, a CRM bolted together with a quoting spreadsheet, an inventory system that doesn't understand fabric widths or pattern repeats. The workarounds become part of the job.
InterioApp started from a different premise: what would a platform look like if it was designed entirely around the way made-to-measure retailers actually work? Five years later, that question has produced a platform spanning quoting, job management, CRM, ordering, workroom documents, online selling, and team collaboration - all speaking the same language, sharing the same data, built for the same business.
Key takeaways
- One platform, eight modules - quoting, jobs, CRM, workroom docs, calendar, online selling, inventory, and communications all share the same data.
- Purpose-built for made-to-measure - fabric calculations, pattern repeats, seam allowances, and treatment-specific measurement worksheets are native, not bolted on.
- Online and in-store unified - the same product library and pricing rules power your showroom quotes and your Shopify store.
- Shopify integration - bi-directional sync means products, orders, and inventory stay consistent across both platforms.
- Works across UK, Australia, NZ, and US - with supplier library imports from TWC, RFMS, CW Systems, and Norman.
This is what's inside.
1. Quote and calculate - a calculation engine that actually speaks your language
The core of any curtain and blind business is the quote. InterioApp's measurement and calculation engine was built with that in mind - it handles the variables that generic quoting software simply cannot.
Every treatment type has its own measurement worksheet. Fabric orientation (vertical, horizontal, railroaded), fullness, seam allowances, hems, returns, overlaps, pattern repeats - all configurable, all calculated automatically per window. Waste can be set as a fixed extra or a percentage. Pricing methods - per metre, per drop, per square metre, or grid-based - are set per template and applied consistently.
Fabric pool system: For larger projects, fabrics can be pooled across multiple windows, giving you accurate total usage and a clear cutting diagram - the kind of detail that matters when you're ordering fabric and briefing your workroom.
Treatment visualisers (13 types), 3D window renderers, and a fabric cutting diagram mean quotes aren't just numbers - they're something you can show a client.
Pricing and templates
- Multiple pricing methods per template
- Pricing grids (size-based)
- Option rules with conditional logic
- Lining, heading and hardware management
- Quote versioning
- Manual line item overrides
- Discount and exclusion controls
- Payment tracking per quote
2. Jobs and projects - from first enquiry to final invoice
Jobs in InterioApp are the central hub that everything else connects to - quotes, measurements, team assignments, documents, communications, purchase orders, and payment records all live in one place per project.
Status workflows with reason tracking mean you always know where a job stands and why it moved. Multiple team members can be assigned across different roles. Notes, activity logs, and project communications are captured automatically as work progresses.
The details that take time aren't the measurements - they're the follow-up, the file-chasing, and the context you lose when a job moves between people.
Duplication detection flags jobs that might already exist. Archiving keeps completed work out of the way without losing history. Grid, list, and table views let different people work the way that suits them.
3. CRM and pipeline - built for long-cycle, high-value clients
Window furnishing clients don't convert in a day. InterioApp's CRM is designed for the way these relationships actually work - lead scoring, pipeline stages, follow-up reminders, and email sequences that keep you present without requiring manual effort for every touchpoint.
- Sales pipeline (Kanban board)
- Lead source tracking and analytics
- Hot leads list
- Automated follow-up reminders
- Email sequences
- Client tags and smart lists
- Activity log and notes per client
- CSV import/export
The CRM connects directly to your calendar, your job records, and your communication history - so when a client calls, everything is already in front of you.
4. Workroom and documents - work orders your workroom will actually use
Generating a cut sheet or workshop document used to mean reformatting a quote into a separate template. In InterioApp, work orders are generated directly from project data - accurate, consistent, and ready to share.
Secure share links with PIN protection let you send work orders to fabricators, installers, or clients without requiring them to have an account. Recipients can leave notes at the item level - feedback flows back into the job record automatically. An audit trail logs every view and every update.
Document builder: The drag-and-drop document system supports dynamic product tables, multi-role signature blocks, QR codes, conditional content, and progress trackers - giving you professional quote documents, not just printouts.
5. Calendar and booking - scheduling that works for in-home consultations
The InterioApp calendar handles the full scheduling lifecycle - from an initial measure appointment booked through your public booking page, through to installation sign-off. Google Calendar and Outlook sync bi-directionally, so your team's schedules stay accurate without double-entry.
The public booking system is Calendly-style: clients pick a time, fill in their details, and receive a confirmation - with calendar links included. Minimum advance notice, buffer times, and availability windows are all configurable per scheduler.
- Daily, weekly and monthly views
- Team member assignment
- Availability editor
- Conflict detection
- Video meeting integration
- Timezone management
- Mobile calendar view
- Calendar analytics
6. Online selling - your Shopify store, connected to your quoting platform
InterioApp's Shopify integration works bi-directionally - products sync between platforms, orders from your Shopify store appear in InterioApp, and your inventory stays consistent across both. For retailers running an online made-to-measure calculator alongside a physical showroom, this closes the gap between digital sales and internal fulfilment.
The built-in online store gives you a client-facing storefront with a page builder, product catalogue, category management, and Stripe payment integration - without requiring a separate platform.
- Shopify bi-directional sync
- Product catalogue
- Page builder
- Stripe payments
- Store analytics
- Custom domain
- Vendor and collection sync
7. Inventory and ordering - fabric, hardware, and materials tracked from library to order
The inventory system is built for the specifics of window furnishing stock: fabric, hardware, materials, wallcovering, and heading tape each have dedicated views. QR codes can be generated and printed for physical tracking. Reorder points trigger low-stock alerts. Purchase orders are created from material queues and tracked through to receipt.
Supplier management, batch ordering, and a lead-time prediction system give you the visibility to order confidently - rather than reactively.
8. Communications - email, SMS, and WhatsApp from one place
Client communications in InterioApp aren't a bolt-on. Email (via SendGrid), SMS, and WhatsApp are all accessible from the client record, the project view, and the calendar - with full history tracked against each contact.
Email campaigns include a deliverability score checker, spam score analysis, and open/click tracking. Custom domain email support means your communications arrive from your address, not a shared sending pool.
