A strong order book is great news - but it does not automatically guarantee stable liquidity. Many mid-sized companies generate solid revenue yet still run into cash crunches because receivables are paid late or not at all. Around 62% of European SMEs now view delayed and unpredictable incoming payments as their biggest current challenge. More than one in two companies have already had to take out a loan as a result.

This guide shows you how to reorganize your accounts receivable and credit management within 30 days so that:

  • Your cash flow remains predictable
  • Outstanding receivables are collected faster
  • Risks are identified early and limited
  • Your finance team is relieved of unnecessary workload

renz credit & consulting (rcc) supports companies in strategically combining liquidity and risk mitigation using instruments such as factoring and financing solutions - independently, objectively, and with a personal touch. This guide provides a concrete 30-day plan you can implement directly in your company - with or without external financing solutions.

Prerequisites: What you need before you start

Before you begin, you should have the following information and basics ready:

  • Access to the accounting system and the open items list (accounts receivable)
  • Current analysis of your top 20 customers by revenue and outstanding receivables
  • Overview of payment terms (standard and individual agreements)
  • Information on existing trade credit insurance, factoring or guarantee agreements (if any)
  • Clear allocation of responsibilities: Who is in charge of accounts receivable, dunning/collections, and customer communication?
  • Management's willingness to adjust processes quickly

Tip: Block out 2-4 hours per week for the next 30 days in which management and finance leaders review and decide on the steps together.

Days 1-7: Create transparency and analyze your starting point

Step 1: Structure your receivables and define key metrics

Start by getting a clear picture of the current situation.

  1. Generate a current open items list (aging report) as of a specific cut-off date.
  2. Prepare an aging analysis of your receivables (for example 0-30, 31-60, 61-90, >90 days past due).
  3. Define 3-5 core KPIs that you will evaluate regularly in future, such as:
    • Days Sales Outstanding (DSO) / average collection period
    • Share of overdue receivables in relation to total receivables
    • Amount and number of receivables past due >60 and >90 days
    • Dunning rate: share of invoices that require reminders

Professional working capital management manages inventory, receivables, and payables to ensure sufficient liquidity for day-to-day operations.

Common mistake: Companies often only analyze receivables after defaults occur. Integrate receivables KPIs firmly into your monthly reporting instead of waiting until a crisis hits.

Step 2: Identify problem areas

Analyze your open items list in a targeted way:

  • Which customers consistently show up with overdue balances?
  • Are there industry or country clusters with longer payment periods?
  • Are certain sales units, locations or product lines particularly affected?

Highlight the most critical 20% of your customers that account for the majority of overdue receivables. Focusing on this segment alone often leads to a noticeable improvement in cash flow.

Tip: Visualize your receivables aging with a bar chart to get a quick overview.

Step 3: Map the process from order to payment receipt

Create a concise process map:

  1. Quote and order approval
  2. Credit check and credit limit allocation
  3. Invoicing (timing, format, requirements)
  4. Payment monitoring
  5. Dunning process and escalation stages
  6. Handover to collections agency or legal department

For each step, note:

  • Responsible person/role
  • Systems/tools used
  • Estimated processing times

Common mistake: Dunning is often treated as a side task within accounting. Clarify who makes the call when key customers are repeatedly late - finance, sales, or management.

Days 8-14: Professionalize dunning and credit checks

Step 4: Structure and streamline the dunning process

Optimize your dunning process:

  1. Define your dunning logic

    • When is the first reminder sent (for example 3-5 days after due date)?
    • How many dunning levels are there, with what tone and what consequences?
    • At what point does personal contact (phone, email) occur?

  2. Revise your message templates

    • Formulate clearly, politely, and firmly
    • State a specific payment date
    • For long-standing customers: offer a conversation instead of threatening measures

  3. Define escalation rules

    • From what amount or level of delinquency is management involved?
    • When is the case handed over to collections, legal counsel, or a factor?

Full-service factoring providers not only cover financing and default risk, they often also take over accounts receivable, dunning, and collections processes. This is attractive for companies that do not want to expand dunning internally.

Tip: Put your dunning rules in writing and train accounting and sales together. A consistent approach is crucial for professional receivables management.

Step 5: Systematize credit checks and credit limits

Systematic credit management starts before goods or services are delivered.

  1. Checks for new customers

    • Which documents do you request (commercial register extract, bank details, references)?
    • Do you obtain a business credit report?

  2. Standardize credit limits

    • Tiered by credit quality, revenue potential, and payment history
    • Clear authorization levels for approvals

  3. Regular review of existing customers

    • Annual credit checks for major customers
    • Event-driven reviews in case of unusual payment behavior or negative industry developments

Professional business information providers deliver structured data on your customers' creditworthiness and form an important basis for safe credit decisions in B2B.

Credit insurers or specialized brokers such as rcc support you in integrating credit limits, credit checks, and suitable coverage concepts into your receivables management.

Common mistake: Only checking creditworthiness for new customers. Especially in volatile markets, a customer's situation can change rapidly.

Days 15-21: Accelerate processes and unlock liquidity

Step 6: Speed up invoicing

Every delay in issuing an invoice extends your collection period.

Review:

  • When is invoicing triggered (based on delivery notes, monthly statements, etc.)?
  • How often are invoices corrected or cancelled?
  • Do formal errors (such as missing documentation) cause delays?

Potential improvements:

  • Switch to prompt, performance-based billing
  • Use checklists for invoice-relevant data early in the process
  • Implement electronic invoicing formats or customer portals

According to studies, incorrect or delayed invoicing is one of the most common reasons for late payments and resulting liquidity bottlenecks among European SMEs.

Tip: Define a service level, for example: "Every delivery is invoiced within two business days." Monitor this regularly in your reporting.

Step 7: Review payment terms and incentives

Analyze your payment terms:

  • Do your payment periods match your risk tolerance?
  • Are there customers with extended terms that strain your liquidity?
  • Are you using early payment discounts or other incentives in a targeted way?

Adjust where necessary:

  • Standardize payment terms (for example 30 days)
  • For higher-risk customers, require prepayment, partial payments, or collateral
  • Offer early payment discounts only where faster cash inflow is particularly beneficial

Warning: Excessive concessions on payment terms for individual key accounts can significantly jeopardize your ability to pay your own obligations.

Step 8: Evaluate financing instruments

Further improve your cash flow with suitable financing tools:

  • Factoring: Sell open receivables to a factor - immediate cash inflow and transfer of default risk, potentially including receivables management. In true factoring, typically 80-90% of the invoice amount is paid out immediately, and the factor assumes the default risk.
  • Trade credit insurance: Protection against bad debt losses, including credit checks and credit limits for your customers. In the event of a claim, credit insurers typically indemnify up to 90% of the insured receivable amount, thus protecting your liquidity.

Independent advice from rcc, specialist broker for trade credit insurance & financing, shows you which instruments best fit your business model.

Days 22-30: Automate, delegate, and establish reporting

Step 9: Consolidate tasks and (partially) outsource

Decide which tasks you want to keep in-house and which you want to outsource:

  • In-house:
    • Credit assessment of strategic key customers
    • Goodwill decisions, special conditions, delivery stops
    • Steering and controlling
  • External:
    • Standardized dunning for smaller amounts
    • Collections at later stages
    • Full takeover of accounts receivable and dunning by a full-service factor

Many factoring models allow you to delegate posting of incoming payments, administrative dunning, and even collections procedures to the factor, freeing you up to focus on your core business.

Factoring and supply chain finance solutions from rcc streamline receivables processes and safeguard liquidity.

Tip: Start with a pilot area before outsourcing processes fully. This keeps you in control and allows you to gather experience.

Step 10: Introduce regular reporting and an early warning system

One-off optimizations are not enough - ongoing monitoring of your receivables is crucial.

Introduce monthly reporting (or bi-weekly in higher-risk environments) covering:

  • DSO
  • Share of overdue receivables by aging bucket
  • Top 10 problem customers
  • Dunning and success rates by dunning level
  • Significant variances versus prior month/plan

Lack of controlling and poor transparency over liquidity are major causes of insolvencies among mid-sized companies. Many insolvencies could be avoided with better financial controlling.

Complement your reporting with a simple early warning system:

  • Traffic-light logic for customers (green/amber/red) based on payment behavior and creditworthiness
  • Clear actions for each color (for example amber = close monitoring, red = delivery stop, use of factoring or trade credit insurance)

Common mistake: KPIs are collected, but no actions follow. Define in advance which thresholds will trigger specific measures.

Next steps: Turn your 30-day project into lasting strength

After 30 days you should:

  • Have a clear overview of your receivables structure and risks
  • Have established documented dunning and credit management processes
  • See initial acceleration in invoicing and incoming payments
  • Have clarity on internal and external roles

Turn this into a lasting advantage:

  • Embed receivables KPIs firmly in monthly reporting to management and shareholders.
  • Review processes at least once a year, and also when your business grows or market conditions change.
  • Consider whether trade credit insurance, guarantees, or factoring could further secure your liquidity or relieve your finance department. You can find more information on the rcc page about trade credit insurance for your receivables business.

FAQ: Common questions about optimizing accounts receivable

How quickly will improvements in accounts receivable show up in cash flow?

The speed depends on your starting point. If invoicing and dunning have been delayed so far, positive effects are often visible within just a few weeks: faster incoming payments, fewer overdue items, and fewer invoice-related queries. If you also deploy instruments such as factoring, your liquidity can improve almost immediately.

Is new software absolutely necessary to achieve improvements?

No. Many improvements - clear dunning logic, explicit responsibilities, standardized templates, regular reports - can be implemented with your existing systems. In the medium to long term, it can make sense to expand automation and interfaces, for example for e-invoicing or automated credit checks, to reduce errors and manual effort.

From what company size does factoring or trade credit insurance make sense?

More important than headcount is the structure of your receivables. Typical users are companies that regularly sell on credit, grant longer payment terms, and build up substantial outstanding receivables - for example in trade, manufacturing, or logistics. As soon as bad debts or volatile incoming payments put your liquidity at risk, you should consider factoring or trade credit insurance.

How do I involve sales in stricter receivables management without losing customers?

Transparency is key. Involve sales early and show that stable cash flow is the foundation for growth and flexibility in pricing or terms. Agree on clear rules - for example, that for "red" customers in your traffic-light system, new orders are only fulfilled against prepayment or with adequate security.
