What invoicing really costs at 100 invoices a month

Part of our guide on online invoicing and payment processing for 250 invoices/month

Calculating invoice pricing at 100 invoices monthly shows when flat fees save money versus free or per-invoice plans with limits.

How much does invoice pricing cost at 20, 50, and 100 invoices?

Invoice pricing depends on your volume and the plan you choose. At 20 invoices monthly, many free or low-tier paid plans suffice. Costs rise as volume grows.

At 100 invoices, flat monthly fees commonly range from $20 to $60, depending on features and user limits. Per-invoice pricing models apply mostly to accounts payable automation products, where fees are publicly stated, but these are uncommon for small business invoicing.

Free plans often limit usage by invoices, users, or clients. For example, Wave’s free plan allows up to 25 invoices per month, Zoho Invoice’s free tier limits 5 customers, and PayPal Invoicing has no monthly fee but charges per transaction. These limits make free plans unsuitable above low volumes.

Additional user seats, client counts, and add-ons can raise costs as your business grows. Many vendors publish fees on their pricing pages, so check these carefully. We cover finding best zapier plan in its own article.

Volume discounts are sometimes available for very large invoice counts but require vendor negotiation. Public pricing usually shows tiers with fixed limits; ask vendors for custom quotes if you exceed those.

What is the average total cost to process one invoice including fees and time?

Total cost per invoice includes subscription, payment processing, and labor time. Payment processors like Stripe and PayPal charge 2.9% plus 30 cents per transaction for cards. ACH transfers usually cost 0.5% capped at $5 per transaction.

Labor cost depends on time spent and your hourly wage. For example, if processing an invoice takes 10 minutes and your labor cost is $30/hr, that’s $5 per invoice. Automation can reduce this time, saving several minutes per invoice. Before you commit to anything, it is worth looking at invoice app pricing.

Add these costs to your software fees and payment charges to find your total per-invoice expense. For a $500 invoice paying 2.9% plus 30 cents, fees are about $15, plus labor and software fees.

Invoice disputes or late payment follow-ups may add labor time. Some platforms like Bill.com include automated reminders; others may charge separately for this service.

Choosing payment methods affects fees. Card payments cost more but are faster; ACH is cheaper but slower. The right mix can lower overall costs. It helps to understand fees per square transaction before going further.

Smaller invoices have higher effective fees due to fixed transaction charges. For example, a $50 invoice incurs roughly $1.75 in card fees, almost 3.5% of the invoice value.

What do free and entry-level invoicing plans include and where do they cap invoices or users?

Free invoicing plans vary. Wave allows 25 invoices per month with unlimited clients, Zoho Invoice limits you to 5 customers but unlimited invoices, and PayPal charges no monthly fee but applies transaction fees per invoice.

Entry-level paid plans costing $10-$30 per month generally allow unlimited invoices, 1-5 users, and a higher client count. These tiers often include basic automation and payment processing integration.

Beyond these limits, vendors require upgrading to higher tiers. Such upgrades often increase user seats, client limits, and advanced features like recurring invoices or detailed reporting.

Add-on features such as advanced reporting or integrations may cost extra. For example, QuickBooks Online charges separately for payroll and advanced reports on top of base plans.

Client limits can force upgrades even when invoice counts remain moderate. For example, Zoho Invoice’s free plan limits clients to 5, requiring paid tiers to bill more.

User counts refer to people who can send or manage invoices. Some vendors charge extra for accountant access or collaborators. Confirm how the vendor defines a user before selecting a plan.

• Wave Free: 25 invoices/month, 1 user, unlimited clients (June 2024)
• Zoho Invoice Free: unlimited invoices, 1 user, 5 clients (June 2024)
• PayPal Invoicing: no monthly fee, transaction fees apply (June 2024)
• $10-$30 plans: usually unlimited invoices, 1-5 users, higher client limits
• Add-ons: reporting, payroll, and integrations often cost extra

How to find the real price: check per-seat, per-client, payment fees, and add-ons before buying

The listed software price rarely covers the whole cost. Payment processing fees often add 1-3% per invoice, depending on your processor and payment method.

Some vendors charge per user, client, or invoice batch. Add-ons such as automated reminders or integrations can add $5 to $15 monthly each.

To model costs, list your invoices, users, and clients. Calculate subscription, payment fees, and any required add-ons before selecting a plan.

Vendors like QuickBooks Online and FreshBooks detail add-on costs on their pricing pages. Check their sites for current add-on prices.

Setup or onboarding fees usually apply to enterprise or custom plans and are quoted individually. Ask vendors directly if applicable.

Payment fees vary by processor. Stripe charges 2.9% plus 30 cents per card transaction, PayPal is similar, and ACH payments typically cost 0.5% capped at $5 per transaction.

1. Determine your monthly invoice volume and average invoice value.
2. Review subscription tiers for invoice, user, and client limits.
3. Estimate payment processing fees based on payment methods and amounts.
4. Calculate labor time savings if using automation.
5. Add all costs to find your total monthly invoicing expense.

Flat monthly vs per-invoice vs free: total cost comparison at typical volumes

Flat monthly subscriptions typically become more cost-effective above 50 invoices. For example, FreshBooks Lite at $15 per month supports unlimited invoices, making it $0.15 per invoice at 100 invoices.

Per-invoice fees suit very low volumes or specialized accounts payable automation. Products like SAP Ariba publish per-document rates for enterprise use but aren’t common for small business invoicing.

Free plans work well for fewer than 25 invoices but impose limits on users or clients that make them impractical beyond that.

At 100 invoices, flat fees offer predictable costs, while per-invoice fees can add up quickly and exceed flat plans in cost.

Common mistakes when estimating invoice pricing costs

Ignoring payment processing and labor time leads to underestimating total costs. Software fees alone rarely cover your full expense.

Assuming free plans scale can cause surprise costs when invoice or user limits force upgrades.

Not accounting for invoice disputes or payment follow-ups may increase labor time and costs.

Failing to test your workflow and volume before choosing a plan can result in unexpected bills.
