Master the Spew monthly bill grid

By Calvin Cottrell, Founder, Spew · · 5 min read

The monthly bill grid is where most Spew users spend most of their time. It's a spreadsheet with superpowers. Here are all the moves, including the ones nobody finds on their own.

The Monthly View is the core of Spew. Every bill you track, every month of the year, every payment, in one spreadsheet-style grid.

Most users spend 80% of their time here. This guide covers every feature, including the shortcuts and power-user moves.

Layout

When you open Monthly View:

Cell states and what they mean

Basic actions

Log a payment

Click any cell. Type the amount paid. Press Enter to save, Esc to cancel.

Edit an existing payment

Click the cell again. Type the new amount. Press Enter.

Delete a payment

Click the cell, clear the value, press Enter. Cell goes back to blank.

Edit a bill’s name, amount, category, or due date

Click the bill name (leftmost column). A detail editor opens. Change any field. Click Save.

Add a new bill

Click the + Add Bill button at the top of the grid. Choose a category, enter name, amount, due date. Save.

Delete a bill

Click the bill name to open the editor. Click Delete. Confirm.

Categories

Your bills are grouped into categories (Housing, Utilities, Subscriptions, etc.). Categories help with:

Manage categories

Click Manage Categories at the top right of the grid:

Common category setups

Simple (fewer categories):

Detailed (more categories):

Pick whatever matches how you think about money. You can change later.

The Avg / Trend column

The rightmost column shows:

Visual cues:

This is the fastest way to spot budget drift. A bill that’s creeping up 5% a month isn’t obvious until you see it in this column.

Partial payments

Some bills get paid in chunks (credit cards, some mortgages). Spew supports this:

  1. Click a cell
  2. Enter the first payment (e.g., $100)
  3. Press Enter
  4. Click the cell again
  5. Click + Add Partial Payment
  6. Enter the second payment (e.g., $50)
  7. Save

The cell now shows $150 total with a “2 payments” indicator. Hover to see the breakdown.

Attachments

Click any cell > Details to attach a receipt, screenshot, or note. Useful for:

Attachments are stored with the payment and visible when you review later.

Sorting and filtering

At the top of the grid:

These don’t modify your data, just the view.

Keyboard shortcuts

The Calendar View

Click Calendar in the sub-nav (within Monthly View). Same data, different layout:

Great for spotting “oh, 5 bills hit on the 1st and my paycheck lands on the 15th” cash-flow issues.

Bank sync and the grid

If you’ve connected a bank, the grid works differently:

The fastest workflow: connect your bank, let Spew auto-fill 70-90% of cells, then manually triage the rest.

Power-user tips

Tip 1: Use the Avg / Trend column for monthly check-ins. Open Monthly View, scroll right. Any red arrows? Investigate. 5 minutes/month to catch drift.

Tip 2: Duplicate bills for irregular categories. Instead of a single “Groceries” bill, create “Groceries (Safeway)” and “Groceries (Costco)” if you want more granular tracking.

Tip 3: Zero out known irregular months. If you won’t pay rent in June (paid annual), put a 0 in that cell so the trend column doesn’t average incorrectly.

Tip 4: Use bill notes for context. Click Details on any cell, add a note like “Negotiated down from $75.” Future-you will thank you.

Tip 5: Pair with forecast. When the forecast shows you’ll go negative in month X, the monthly grid is where you decide what to cut or shift.
