Rough estimate for the first 90 days, not financial advice.
First 3 steps
Interview 10 home bakers from Instagram and local Facebook groups about how they track weekend orders today.
Ask each baker to show you their last Friday-night mess of screenshots, notes, or chat threads.
Sketch the order list screen and the 'due tomorrow' view on paper or in Figma, then test the sketches with 5 of those bakers.
The Pitch
Saturday Crumb is a mobile app for home bakers and makers who take weekend orders through Instagram and WhatsApp DMs, turning a mess of screenshots and scrolling into one calm, scannable list. Paste a message or tap a few quick fields to log who ordered, how many, and when they're picking up, then check off "paid" and "ready" as the week goes on, with everything sorted by pickup time and a "due tomorrow" view waiting for you on Friday night. There are no storefronts, no inventory, and no payment processing, so you keep collecting money directly from customers exactly as you do today, with zero transaction fees. Saturday Crumb is free for up to 20 orders per week, and Saturday Crumb Plus is $6 per month for unlimited orders, customer history, and a shareable order-form link, so by Saturday morning nothing is lost and you can pour your coffee with quiet confidence.
For Whom
A solo home baker in her kitchen on Friday night, flour on her phone case, takes 15 to 60 weekend orders through Instagram and WhatsApp DMs and currently scrolls back through chat threads, screenshots, and a half-finished notes app to piece together who paid, how many dozen they wanted, and when they're coming by, because one missed order costs her income and the reputation she has built by word of mouth.

Saturday Crumb: The Weekend List
Due tomorrow: 9 orders, first pickup 8:30 AM
Orders are sorted by pickup time. Each row shows the customer, item count, amount, a paid checkmark and a ready checkmark. Unpaid orders glow orange so you can nudge them Friday night, not Saturday at the door.
Quick-add order sheet: type a customer name, item, quantity, and pickup time in under 15 seconds, or paste a DM straight into a notes field and fill in the details beside it
One weekend order list sorted by pickup time, with each row showing customer name, items, quantity, paid status, and pickup slot at a glance
Tap-to-toggle Paid and Ready checkmarks on every order, with a running count of orders still unpaid and still unfinished
Due Tomorrow view: a Friday-night summary of every order pickup-bound for Saturday and Sunday, with total quantity per item so you know exactly how many of each to bake
Free tier of up to 20 orders per week, with Saturday Crumb Plus at $6 per month unlocking unlimited orders, customer history, and a shareable order-form link
Shareable order-form link (Plus): customers fill in item, quantity, and preferred pickup time, and their order lands in your list automatically instead of getting buried in a DM thread
Customer history (Plus): tap a name to see past orders, usual quantities, and notes like allergies, so repeat customers can be re-entered in two taps

aiOptional, lightweight parsing of pasted DM text into structured order fields (customer name, item, quantity, pickup time) using an LLM API such as OpenAI GPT-4o mini with a strict JSON schema. The baker always confirms before saving, and the parser falls back to manual quick fields if it is unavailable or unsure.dataPostgres tables for bakers, customers, orders (items, quantity, paid flag, ready flag, pickup time, source such as Instagram or WhatsApp, notes) and order_form_links. Local-first caching with SQLite or WatermelonDB gives offline access on Friday nights, with background sync to Supabase. Customer history is stored for Plus users, and PostHog tracks product analytics.backendSupabase (Postgres, Auth, Row Level Security, Edge Functions) for sign-in, order CRUD, and enforcing the free-tier cap of 20 orders per week versus unlimited orders on Plus.

Ask each baker to show you their last Friday-night mess of screenshots, notes, or chat threads.
Sketch the order list screen and the 'due tomorrow' view on paper or in Figma, then test the sketches with 5 of those bakers.
Run a manual pilot for one weekend by logging 3 bakers' orders in a shared spreadsheet and sending them a daily summary.
Set up a simple waitlist page and ask pilot bakers whether they would pay $6 per month for unlimited orders, customer history, and a shareable order-form link.

Security & Threat Model
Sensitive data
Customer names and phone numbers/handlesAllergy notes in customer historyPasted DM text containing personal detailsPaid status and order amountsPickup times and home pickup address
Roles & permissions
Baker (account owner)— Create, edit, delete own orders and customers; manage subscription; create and revoke own order-form link.
Anonymous customer (order-form visitor)— Submit one order through the baker's link only; cannot view any orders, customers, or other submissions.
Helper (optional invited)— View today's list and toggle Paid/Ready; cannot export, delete, view customer history, or change billing.
Support staff— View account metadata only; access order content solely with the baker's time-limited consent, logged.
Abuse cases
⚠ Public order-form link is guessed or scraped, letting strangers read orders or flood the baker's list with fake orders.
Mitigation
Use long random unguessable tokens, make the form write-only, rate-limit and add CAPTCHA, hold new submissions as pending, and let bakers rotate or disable the link.
⚠ Pickup address or customer contact details leak to other customers through the form, confirmations, or shared screens.
Mitigation
Show the pickup address only in the baker's own confirmation message, never on the public form; return no order data to submitters beyond their own receipt.
⚠ Allergy notes are lost, edited wrongly, or hidden, causing a customer to receive an unsafe item.
Mitigation
Show allergy flags on the order row and Due Tomorrow view, keep an edit history, and include a non-medical disclaimer that the baker stays responsible.
⚠ Free-tier cap bypass or downgrade lockout hides or deletes existing orders just before Saturday.
Mitigation
Never delete or hide orders on downgrade or cap; allow viewing and exporting everything and block only new entries, with the cap enforced server-side.
⚠ Pasted DM text or Plus data is stored in plaintext logs or crash reports, and is exposed if an account is taken over.
Mitigation
Exclude notes fields from logs and analytics, require verified login with session revocation, and delete all customer data within 30 days of account deletion.
Compliance
GDPR/UK GDPR and CCPA for customer personal data; no PCI scope since payments are handled outside the app; WhatsApp reminder upsell needs opt-in consent (TCPA/WhatsApp Business policy).
Must pass before launch
☐ An unauthenticated request to any order-form token endpoint cannot read orders, and submissions beyond the rate limit (e.g. 10 per minute per IP) are rejected.
☐ Baker A cannot fetch, edit, or list Baker B's orders or customers by changing IDs in API requests; every attempt returns 403 or 404.
☐ Downgrading from Plus to Free leaves all existing orders and customer history viewable and exportable, and only blocks creating orders past 20 per week.
☐ Rotating the order-form link makes the old URL return an error immediately, and customer notes never appear in server logs or analytics events.
